+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+`FormArgument` is based on the `Fix` type from `recursion-schemes` which is used
+by some of the frontend code.

+This is the code responsible for generating endpoint argument forms

+(the commit is fixed here for convenience)

+The PureScript frontend uses Halogen to generate HTML, here is the example:

+# Introduction
+
+This document describes a set of standards for all code under the Plutus Use Cases
+project. It also explains our reasoning for these choices, and acts as a living
+document of our practices for current and future contributors to the project. We
+intend for this document to evolve as our needs change, as well as act as a
+single point of truth for standards.
+
+# Motivation
+
+The desired outcomes from the prescriptions in this document are as follows.
+
+## Increase consistency
+
+Inconsistency is worse than _any_ standard, as it requires us to track a large
+amount of case-specific information. Software development is already a difficult
+task due to the inherent complexities of the problems we seek to solve, as well
+as the inherent complexities foisted upon us by _decades_ of bad historical
+choices we have no control over. For newcomers to a project and old hands alike,
+increased inconsistency translates to developmental friction, resulting in
+wasted time, frustration and ultimately, worse outcomes for the code in
+question.
+
+To avoid putting ourselves into this boat, both currently and in the future, we
+must strive to be _automatically consistent_. Similar things should look
+similar; different things should look different; as much as possible, we must
+pick some rules _and stick to them_; and this has to be clear, explicit and
+well-motivated. This will ultimately benefit us, in both the short and the long
+term. The standards described here, as well as this document itself, is written
+with this foremost in mind.
+
+## Limit non-local information
+
+There is a limited amount of space in a developer's skull; we all have bad days,
+and we forget things or make decisions that, perhaps, may not be ideal at the
+time. Therefore, limiting cognitive load is good for us, as it reduces the
+amount of trouble we can inflict due to said skull limitations. One of the worst
+contributors to cognitive load (after inconsistency) is _non-local information_
+- the requirement to have some understanding beyond the scope of the current
+unit of work. That unit of work can be a data type, a module, or even a whole
+project; in all cases, the more non-local information we require ourselves to
+hold in our minds, the less space that leaves for actually doing the task at
+hand, and the more errors we will introduce as a consequence.
+
+Thus, we must limit the need for non-local information at all possible levels.
+'Magic' of any sort must be avoided; as much locality as possible must be
+present everywhere; needless duplication of effort or result must be avoided.
+Thus, our work must be broken down into discrete, minimal, logical units, which
+can be analyzed, worked on, reviewed and tested in as much isolation as
+possible. This also applies to our external dependencies.
+
+Thus, many of the decisions described here are oriented around limiting the
+amount of non-local knowledge required at all levels of the codebase.
+Additionally, we aim to avoid doing things 'just because we can' in a way that
+would be difficult for other Haskellers to follow, regardless of skill level.
+
+## Minimize impact of legacy
+
+Haskell is a language that is older than some of the people currently writing
+it; parts of its ecosystem are not exempt from it. With age comes legacy, and
+much of it is based on historical decisions which we now know to be problematic
+or wrong. We can't avoid our history, but we can minimize its impact on our
+current work. 
+
+Thus, we aim to codify good practices in this document _as seen today_. We also
+try to avoid obvious 'sharp edges' by proscribing them away in a principled,
+consistent and justifiable manner. 
+
+## Automate away drudgery
+
+As developers, we should use our tools to make ourselves as productive as
+possible. There is no reason for us to do a task if a machine could do it for
+us, especially when this task is something boring or repetitive. We love Haskell
+as a language not least of all for its capability to abstract, to describe, and
+to make fun what other languages make dull or impossible; likewise, our work
+must do the same.
+
+Many of the tool-related proscriptions and requirements in this document are
+driven by a desire to remove boring, repetitive tasks that don't need a human to
+perform. By removing the need for us to think about such things, we can focus on
+those things which _do_ need a human; thus, we get more done, quicker.
+
+# Conventions
+
+The words MUST, SHOULD, MUST NOT, SHOULD NOT and MAY are defined as per [RFC
+2119][rfc-2119].
+
+# Tools
+
+## Compiler warning settings
+
+The following warnings MUST be enabled for all builds of any project, or any
+project component:
+
+* ``-Wall``
+* ``-Wcompat``
+* ``-Wincomplete-uni-patterns``
+* ``-Wredundant-constraints``
+* ``-Werror``
+
+Additionally, ``-Wincomplete-record-updates`` SHOULD be enabled for all builds
+of any project. The only exception is when this warning would be spuriously
+triggered by ``record-dot-preprocessor``, which occurs for definitions like
+this:
+
+```haskell
+data Foo = Bar {
+   baz :: Int,
+   quux :: String
+   } | 
+   Quux
+```
+
+Additionally, ``-Wredundant-constraints`` SHOULD be enabled for all builds of
+any project. Exceptions are allowed when the additional constraints are designed
+to ensure safety, rather than due to reliance on any method.
+
+If a warning from this list is to be disabled, it MUST be disabled in the
+narrowest possible scope; ideally, this SHOULD be a single module.
+
+### Justification
+
+These options are suggested by [Alexis King][alexis-king-options] - the
+justifications for them can be found at the link. These fit well with our
+motivations, and thus, should be used everywhere. The ``-Werror`` ensures that
+warnings _cannot_ be ignored: this means that problems get fixed sooner.
+
+The two permissible exceptions stem from limitations in the record-dot plugin
+(for ``-Wincomplete-record-updates``) and from the way redundant constraints are
+detected; basically, unless a type class method from a constraint is used within
+the body of the definition, or is required by anything called in a transitive
+manner, the constraint is deemed redundant. Mostly, this is accurate, but some
+type-level safety constraints can be deemed redundant as a result of this
+approach. In this case, a limited lowering (per module ideally) of those two
+warnings is acceptable, as they represent workarounds to technical problems,
+rather than issues with the warnings themselves.
+
+## Linting
+
+Every source file MUST be free of warnings as produced by [HLint][hlint], with
+default settings.
+
+### Justification
+
+HLint automates away the detection of many common sources of boilerplate and
+inefficiency. It also describes many useful refactors, which in many cases make
+the code easier to read and understand. As this is fully automatic, it saves
+effort on our part, and ensures consistency across the codebase without us
+having to think about it.
+
+## Code formatting
+
+Every source file MUST be formatted according to [Fourmolu][fourmolu], with the
+following settings (as per its settings file):
+
+* ``indentation: 2``
+* ``comma-style: leading``
+* ``record-brace-space: true``
+* ``indent-wheres: true``
+* ``diff-friendly-import-export: true``
+* ``respectful: true``
+* ``haddock-style: multi-line``
+* ``newlines-between-decls: 1``
+
+Each source code line MUST be at most 100 characters wide, and SHOULD
+be at most 80 characters wide.
+
+### Justification
+
+Consistency is the most important goal of readable codebases. Having a single
+standard, automatically enforced, means that we can be sure that everything will
+look similar, and not have to spend time or mind-space ensuring that our code
+complies. Additionally, as Ormolu is opinionated, anyone familiar with its
+layout will find our code familiar, which eases the learning curve.
+
+Lines wider than 80 characters become difficult to read, especially when viewed
+on a split screen. Sometimes, we can't avoid longer lines (especially with more
+descriptive identifiers), but a line length of over 100 characters becomes
+difficult to read even without a split screen. We don't _enforce_ a maximum of
+80 characters for this exact reason; some judgment is allowed.
+
+# Code practices
+
+## Naming
+
+camelCase MUST be used for all non-type, non-data-constructor names; otherwise,
+TitleCase MUST be used. Acronyms used as part of a naming identifier (such as 
+'JSON', 'API', etc) SHOULD be downcased; thus ``repairJson`` and
+``fromHttpService`` are correct. Exceptions are allowed for external libraries
+(Aeson's ``parseJSON`` for example).
+
+### Justification
+
+camelCase for non-type, non-data-constructor names is a long-standing convention
+in Haskell (in fact, HLint checks for it); TitleCase for type names or data
+constructors is _mandatory_. Obeying such conventions reduces cognitive load, as
+it is common practice among the entire Haskell ecosystem. There is no particular
+standard regarding acronym casing: examples of always upcasing exist (Aeson) as
+well as examples of downcasing (``http-api-data``). One choice for consistency
+(or as much as is possible) should be made however.
+
+## Modules
+
+All publically facing modules (namely, those which are not listed in
+``other-modules`` in the Cabal file) MUST have explicit export lists.
+
+All modules MUST use one of the following conventions for imports:
+
+* ``import Foo (Baz, Bar, quux)``
+* ``import qualified Foo as F``
+
+Data types from qualified-imported modules SHOULD be imported unqualified by
+themselves:
+
+```haskell
+import Data.Vector (Vector)
+import qualified Data.Vector as Vector
+```
+
+The main exception is if such an import would cause a name clash:
+
+```haskell
+-- no way to import both of these without clashing the Vector type name
+import qualified Data.Vector as Vector
+import qualified Data.Vector.Storable as VStorable
+```
+
+The _sole_ exception is a 'hiding import' to replace part of the functionality
+of ``Prelude``:
+
+```haskell
+-- replace the String-based readFile with a Text-based one
+import Prelude hiding (readFile)
+import Data.Text.IO (readFile)
+```
+
+Data constructors SHOULD be imported individually. For example, given the
+following data type declaration:
+
+```haskell
+module Quux where
+
+data Foo = Bar Int | Baz
+```
+
+Its corresponding import should be:
+
+```haskell
+import Quux (Foo, Bar, Baz)
+```
+
+For type class methods, the type class and its methods MUST be imported
+as so:
+
+```haskell
+import Data.Aeson (FromJSON (fromJSON))
+```
+
+Qualified imports SHOULD use the entire module name (that is, the last component
+of its hierarchical name) as the prefix. For example:
+
+```haskell
+import qualified Data.Vector as Vector
+```
+
+Exceptions are granted when:
+
+* The import would cause a name clash anyway (such as different ``vector``
+  modules); or
+* We have to import a data type qualified as well.
+
+### Justification
+
+Explicit export lists are an immediate, clear and obvious indication of what
+publically visible interface a module provides. It gives us stability guarantees
+(namely, we know we can change things that aren't exported and not break
+downstream code at compile time), and tells us where to go looking first when
+inspecting or learning the module. Additionally, it means there is less chance
+that implementation details 'leak' out of the module due to errors on the part
+of developers, especially new developers.
+
+One of the biggest challenges for modules which depend on other modules
+(especially ones that come from the project, rather than an external library) is
+knowing where a given identifier's definition can be found. Having explicit
+imports of the form described helps make this search as straightforward as
+possible. This also limits cognitive load when examining the sources (if we
+don't import something, we don't need to care about it in general). Lastly,
+being explicit avoids stealing too many useful names.
+
+In general, type names occur far more often in code than function calls: we have
+to use a type name every time we write a type signature, but it's unlikely we
+use only one function that operates on said type. Thus, we want to reduce the
+amount of extra noise needed to write a type name if possible. Additionally,
+name clashes from function names are far more likely than name clashes from type
+names: consider the number of types on which a ``size`` function makes sense.
+Thus, importing type names unqualified, even if the rest of the module is
+qualified, is good practice, and saves on a lot of prefixing.
+
+## Plutus module import naming conventions
+
+In addition to the general module import rules, we should follow some conventions on how we import the Plutus API modules, allowing for some flexibility depending on the needs of a particular module.
+
+Modules under the names `Plutus`, `Ledger` and `Plutus.V1.Ledger` SHOULD be imported qualified with their module name, as per the general module standards. An exception to this is `Plutus.V1.Ledger.Api`, where the `Ledger` name is preferred.
+
+Some other exceptions to this are allowed where it may be more convenient to avoid longer qualified names.
+
+
+For example:
+
+```haskell
+import Plutus.V1.Ledger.Slot qualified as Slot
+import Plutus.V1.Ledger.Tx qualified as Tx
+import Plutus.V1.Ledger.Api qualified as Ledger
+import Ledger.Oracle qualified as Oracle
+import Plutus.Contract qualified as Contract
+```
+
+In some cases it may be justified to use a shortened module name:
+
+```haskell
+import Plutus.V1.Ledger.AddressMap qualified as AddrMap
+```
+
+Modules under `PlutusTx` that are extensions to `PlutusTx.Prelude` MAY be imported unqualified when it is reasonable to do so. 
+
+The `Plutus.V1.Ledger.Api` module SHOULD be avoided in favour of more specific modules where possible.
+
+For example, we should avoid:
+
+```haskell
+import Plutus.V1.Ledger.Api qualified as Ledger (ValidatorHash)
+```
+
+In favour of:
+
+```haskell
+import Plutus.V1.Ledger.Scripts qualified as Scripts (ValidatorHash)
+```
+
+### Justification
+
+The Plutus API modules can be confusing, with numerous modules involved, many exporting the same items. 
+
+Consistent qualified names help ease this problem, and decrease ambiguity about where imported items come from.
+
+
+## LANGUAGE pragmata
+
+The following pragmata MUST be enabled at project level (that is, in
+``package.yaml``):
+
+* ``BangPatterns``
+* ``BinaryLiterals``
+* ``ConstraintKinds``
+* ``DataKinds``
+* ``DeriveFunctor``
+* ``DeriveGeneric``
+* ``DeriveTraversable``
+* ``DerivingStrategies``
+* ``DuplicateRecordFields``
+* ``EmptyCase``
+* ``FlexibleContexts``
+* ``FlexibleInstances``
+* ``GADTs``
+* ``GeneralizedNewtypeDeriving``
+* ``HexFloatLiterals``
+* ``InstanceSigs``
+* ``ImportQualifiedPost``
+* ``KindSignatures``
+* ``LambdaCase``
+* ``MultiParamTypeClasses``
+* ``NoImplicitPrelude``
+* ``NumericUnderscores``
+* ``OverloadedStrings``
+* ``StandaloneDeriving``
+* ``TupleSections``
+* ``TypeApplications``
+* ``TypeOperators``
+* ``TypeSynonymInstances``
+* ``UndecidableInstances``
+
+Any other LANGUAGE pragmata MUST be enabled per-file. All language pragmata MUST
+be at the top of the source file, written as ``{-# LANGUAGE PragmaName #-}``.
+
+Furthermore, the following pragmata MUST NOT be used, or enabled, anywhere:
+
+* ``DeriveDataTypeable``
+* ``DeriveFoldable``
+* ``PartialTypeSignatures``
+* ``PostfixOperators``
+
+### Justification
+
+``DataKinds``, ``DuplicateRecordFields``, ``GADTs``, ``TypeApplications``,
+``TypeSynonymInstances`` and ``UndecidableInstances`` are needed globally to use
+the GHC plugin from ``record-dot-preprocessor``. While some of these extensions
+are undesirable to use globally, we end up needing them anyway, so we can't
+really avoid this.
+
+``BangPatterns`` are a much more convenient way to force evaluation than
+repeatedly using `seq`. Furthemore, they're not confusing, and are considered
+ubiquitous enough for ``GHC2021``. Having them on by default simplifies a lot of
+performance tuning work, and they don't really need signposting.
+
+``BinaryLiterals``, ``HexFloatLiterals`` and ``NumericUnderscores`` all simulate
+features that are found in many other programming languages, and that are
+extremely convenient in a range of settings, ranging from dealing with large
+numbers to bit-twiddling. If anything, it is more surprising and annoying when
+these _aren't_ enabled, and should really be part of Haskell syntax anyway.
+Enabling this project-wide actually encourages better practice and readability.
+
+The kind ``Constraint`` is not in Haskell2010, and thus, isn't recognized by
+default. While working with constraints as first-class objects isn't needed
+often, this extension effectively exists because Haskell2010 lacks exotic kinds
+altogether. Since we require explicit kind signatures (and foralls) for all type
+variables, this needs to be enabled as well. There is no harm in enabling this
+globally, as other rich kinds (such as ``Symbol`` or ``Nat``) don't require an
+extension for their use, and this doesn't change any behaviour (``Constraint``
+exists whether you enable this extension or not, as do 'exotic kinds' in
+general).
+
+``DerivingStrategies`` is good practice (and in fact, is mandated by this
+document); it avoids ambiguities between ``GeneralizedNewtypeDeriving`` and
+``DeriveAnyClass``, allows considerable boilerplate savings through use of
+``DerivingVia``, and makes the intention of the derivation clear on immediate
+reading, reducing the amount of non-local information about derivation
+priorities that we have to retain. ``DeriveFunctor`` and
+``GeneralizedNewtypeDeriving`` are both obvious and useful extensions to the
+auto-derivation systems available in GHC. Both of these have only one correct
+derivation (the former given by [parametricity
+guarantees][functor-parametricity], the latter by the fact that a newtype only
+wraps a single value). As there is no chance of unexpected behaviour by these,
+no possible behaviour variation, and that they're key to supporting both the
+``stock`` and ``newtype`` deriving stratgies, having these on by default removes
+considerable tedium and line noise from our code. A good example are newtype
+wrappers around monadic stacks:
+
+```haskell
+newtype FooM a = FooM (ReaderT Int (StateT Text IO) a)
+  deriving newtype (
+    Functor, 
+    Applicative, 
+    Monad, 
+    MonadReader Int, 
+    MonadState Text, 
+    MonadIO
+    )
+```
+
+Deriving ``Traversable`` is a little tricky. While ``Traversable`` is lawful
+(though not to the degree ``Functor`` is, permitting multiple implementations in
+many cases), deriving it is complicated by issues of role assignation for
+higher-kinded type variables and the fact that you can't ``coerce`` through a
+``Functor``. These are arguably implementation issues, but repairing this
+situation requires cardinal changes to ``Functor``, which is unlikely to ever
+happen. Even newtype or via derivations of ``Traversable`` are mostly
+impossible; thus, we must have special support from GHC, which
+``DeriveTraversable`` enables. This is a very historically-motivated
+inconsistency, and should really not exist at all. While this only papers over
+the problem (as even with this extension on, only stock derivations become
+possible), it at least means that it can be done at all. Having it enabled
+globally makes this inconsistency slightly less visible, and is completely safe.
+
+While GHC ``Generic``s are far from problem-free, many parts of the Haskell
+ecosystem require ``Generic``, either as such (c.f. ``beam-core``) or for
+convenience (c.f ``aeson``, ``hashable``). Additionally, several core parts of
+Plutus (including ``ToSchema``) are driven by ``Generic``. The derivation is
+trivial in most cases, and having to enable an extension for it is quite
+annoying. Since no direct harm is done by doing this, and use of ``Generic`` is
+already signposted clearly (and is mostly invisible), having this on globally
+poses no problems.
+
+``EmptyCase`` not being on by default is an inconsistency of Haskell 2010, as
+the report allows us to define an empty data type, but without this extension,
+we cannot exhaustively pattern match on it. This should be the default behaviour
+for reasons of symmetry.
+
+``FlexibleContexts`` and ``FlexibleInstances`` paper over a major deficiency of
+Haskell2010, which in general isn't well-motivated. There is no real reason to
+restrict type arguments to variables in either type class instances or type
+signatures: the reasons for this choice in Haskell2010 are entirely for the
+convenience of the implementation. It produces no ambiguities, and in many ways,
+the fact this _isn't_ the default is more surprising than anything.
+Additionally, many core libraries rely on one, or both, of these extensions
+being enabled (``mtl`` is the most obvious example, but there are many others).
+Thus, even for popularity and compatibility reasons, these should be on by
+default.
+
+``InstanceSigs`` are harmless by default, and introduce no complications. Their
+not being default is strange. ``ImportQualifiedPost`` is already a convention 
+of this project, and helps with formatting of imports. 
+
+``KindSignatures`` become extremely useful in any setting where 'exotic kinds'
+(meaning, anything which isn't `Type` or `Type -> Type` or similar) are
+commonplace; much like type signatures clarify expectations and serve as active
+documentation (even where GHC can infer them), explicit kind signatures serve
+the same purpose 'one level up'. When combined with the requirement to provide
+explicit foralls for type variables defined in this document, they simplify the
+usage of 'exotic kinds' and provide additional help from both the type checker
+and the code. Since this project is Plutus-based, we use 'exotic kinds'
+extensively, especially in row-polymorphic records; thus, in our case, this is
+especially important. This also serves as justification for
+`ScopedTypeVariables`, as well as ironing out a weird behaviour where in cases
+such as 
+
+```haskell
+foo :: a -> b
+foo = bar . baz
+   where
+      bar :: String -> b
+      bar = ...
+      baz :: a -> String
+      baz = ...
+```
+
+cause GHC to produce _fresh_ type variables in each ``where``-bind. This is
+confusing and makes little sense - if the user wanted a fresh variable, they
+would name it that way. What's worse is that the type checker emits an error
+that makes little sense (except to those who have learned to look for this
+error), creating even more confusion, especially in cases where the type
+variable is constrained:
+
+```haskell
+foo :: (Monoid m) => m -> String
+foo = bar . baz
+   where
+      baz :: m -> Int
+      baz = ... -- this has no idea that m is a Monoid, since m is fresh!
+```
+
+``LambdaCase`` reduces a lot of code in the common case of analysis of sum
+types. Without it, we are forced to either write a dummy ``case`` argument:
+
+```haskell
+foo s = case s of
+-- rest of code here
+```
+
+Or alternatively, we need multiple heads:
+
+```haskell
+foo Bar = -- rest of code
+foo (Baz x y) = -- rest of code
+-- etc
+```
+
+``LambdaCase`` is shorter than both of these, and avoids us having to bind
+variables, only to pattern match them away immediately. It is convenient, clear
+from context, and really should be part of the language to begin with.
+
+``MultiParamTypeClasses`` are required for a large number of standard Haskell
+libraries, including ``mtl`` and ``vector``, and in many situations. Almost any
+project of non-trivial size must have this extension enabled somewhere, and if
+the code makes significant use of ``mtl``-style monad transformers or defines
+anything non-trivial for ``vector``, it must use it. Additionally, it arguably
+lifts a purely implementation-driven decision of the Haskell 2010 language, much
+like ``FlexibleContexts`` and ``FlexibleInstances``. Lastly, although it can
+introduce ambiguity into type checking, it only applies when we want to define
+our own multi-parameter type classes, which is rarely necessary. Enabling it
+globally is thus safe and convenient.
+
+Based on the recommendations of this document (driven by the needs of the
+project and the fact it's cardinally connected with Plutus),
+``NoImplicitPrelude`` is required to allow us to default to the Plutus prelude
+instead of the one from ``base``.
+
+``OverloadedStrings`` deals with the problem that ``String`` is a suboptimal
+choice of string representation for basically _any_ problem, with the general
+recommendation being to use ``Text`` instead. It is not, however, without its
+problems: 
+
+* ``ByteString``s are treated as ASCII strings by their ``IsString`` instance;
+* Overly polymorphic behaviour of many functions (especially in the presence of
+  type classes) forces extra type signatures;
+
+These are usually caused not by the extension itself, but by other libraries and
+their implementations of either ``IsString`` or overly polymorphic use of type
+classes without appropriate laws (Aeson's ``KeyValue`` is a particularly
+egregious offender here). The convenience of this extension in the presence of
+literals, and the fact that our use cases mostly covers ``Text``, makes it worth
+using by default.
+
+``StandaloneDeriving`` is mostly needed for GADTs, or situations where complex
+type-level computations drive type class instances, requiring users to specify
+constraints manually. This can pose some difficulties syntactically (such as
+with deriving strategies), but isn't a problem in and of itself, as it doesn't
+really change how the language works. Having this enabled globally is not
+problematic.
+
+``TupleSections`` smooths out an oddity in the syntax of Haskell 2010 regarding
+partial application of tuple constructors. Given a function like ``foo :: Int -> String ->
+Bar``, we accept it as natural that we can write ``foo 10`` to get a function of
+type ``String -> Bar``. However, by default, this logic doesn't apply to tuple
+constructors. As special cases are annoying to keep track of, and in this case,
+serve no purpose, as well as being clear from their consistent use, this should
+also be enabled by default; it's not clear why it isn't already.
+
+``TypeOperators`` is practically a necessity when dealing with type-level
+programming seriously. Much how infix data constructors are extremely useful
+(and sometimes clearer than their prefix forms), infix _type_ constructors serve
+a similar functionality. Additionally, Plutus relies on operators at the type
+level significantly - for example, it's not really possible to define a
+row-polymorphic record or variant without them. Having to enable this almost
+everywhere is a needless chore, and having type constructors behaving
+differently to data constructors here is a needless source of inconsistency.
+
+We exclude ``DeriveDataTypeable``, as ``Data`` is a strictly-worse legacy
+version of ``Generic``, and ``Typeable`` no longer needs deriving for anything
+anyway. The only reason to derive either of these is for compatibility with
+legacy libraries, which we don't have any of, and the number of which shrinks
+every year. If we're using this extension at all, it's probably a mistake.
+
+``Foldable`` is possibly the most widely-used, lawless type class. Its only laws
+are about self-consistency (such as agreement between ``foldMap`` and
+``foldr``), but unlike something like ``Functor``, ``Foldable`` doesn't have any
+laws specifying its behaviour outside of 'it compiles'. As a result, even if we
+accept its usefulness (a debatable position in itself), there are large numbers
+of possible implementations that could be deemed 'valid'. The approach taken by
+``DeriveFoldable`` is _one_ such approach, but this requires knowing its
+derivation algorithm, and may well not be something you need. Unlike a
+``Functor`` derivation (whose meaning is obvious), a ``Foldable`` one is
+anything but, and requires referencing a lot of non-local information to
+determine how it will behave (especially for the 'richer' ``Foldable``, with
+many additional methods). If you need a ``Foldable`` instance, you will either
+newtype or via-derive it (which doesn't need this extension anyway), or you'll
+write your own (which _also_ doesn't need this extension). Enabling this
+encourages bad practices, is confusing, and ultimately doesn't really benefit
+anything.
+
+``PartialTypeSignatures`` is a misfeature. Allowing leaving in type holes (to be
+filled by GHC's inference algorithm) is an anti-pattern for the same reason that
+not providing top-level signatures: while it's possible (mostly) for GHC to
+infer signatures, we lose considerable clarity and active documentation by doing
+so, in return for (quite minor) convenience. While the use of typed holes during
+development is a good practice, they should not remain in final code. Given that
+Plutus projects require us to do some fairly advanced type-level programming
+(where inference often _fails_), this extension can often provide totally
+incorrect results due to GHC's 'best-effort' attempts at type checking. There is
+no reason to leave behind typed holes instead of filling them in, and we
+shouldn't encourage this.
+
+``PostfixOperators`` are arguably a misfeature. Infix operators already require
+a range of special cases to support properly (what symbols create an infix
+operator, importing them at the value and type level, etc), which postfix
+operators make _worse_. Furthermore, they are seldom, if ever, used, and
+typically aren't worth the trouble. Haskell is not Forth, none of our
+dependencies rely on postfix operators, and defining our own creates more
+problems than it solves.
+
+## ``record-dot-preprocessor``
+
+The GHC plugin from ``record-dot-preprocessor`` SHOULD be enabled globally. 
+
+### Justification
+
+Haskell records are documentedly and justifiably subpar: the [original issue for
+the record dot preprocessor extension][rdp-issue] provides a good summary of the
+reasons. While a range of extensions (including ``DuplicateRecordFields``,
+``DisambiguateRecordFields``, ``NamedFieldPuns``, and many others) have been
+proposed, and accepted, to mitigate the situation, the reality is that, even
+with them in place, use of records in Haskell is considerably more difficult,
+and less flexible, than in any other language in widespread use today. The
+proposal described in the previous link provides a solution which is familiar to
+users of most other languages, and addresses the fundamental issue that makes
+Haskell records so awkward.
+
+While the proposal for the record dot syntax that this preprocessor enables is
+coming, it's not available in the current version of Haskell used by Plutus (and
+thus, transitively, by us). Additionally, the earliest this will be available is
+GHC 9.2, and given that our dependencies must support this version too, it'll be
+considerable time before we can get its benefits. The preprocessor gives us
+these benefits immediately, at some dependency cost. While it's not a perfect
+process, as it involves enabling several questionable extensions, and can
+require disabling an important warning, it significantly reduces issues with
+record use, making it worthwhile. Additionally, when GHC 9.2 becomes usable, we
+can upgrade to it seamlessly.
+
+## Prelude
+
+The ``PlutusTx.Prelude`` MUST be used. A 'hiding import' to remove functionality
+we want to replace SHOULD be used when necessary. If functionality from the
+``Prelude`` in ``base`` is needed, it SHOULD be imported qualified. Other
+preludes MUST NOT be used.
+
+### Justification
+
+As this is primarily a Plutus project, we are in some ways limited by what
+Plutus requires (and provides). Especially for on-chain code, the Plutus prelude
+is the one we need to use, and therefore, its use should be as friction-free as
+possible. As many modules may contain a mix of off-chain and on-chain code, we
+also want to make impendance mismatches as limited as possible.
+
+By the very nature of this project, we can assume a familiarity (or at least,
+the goal of such) with Plutus stuff. Additionally, _every_ Haskell developer is
+familiar with the ``Prelude`` from ``base``. Thus, any replacements of the
+Plutus prelude functionality with the ``base`` prelude should be clearly
+indicated locally.
+
+Haskell is a 30-year-old language, and the ``Prelude`` is one of its biggest
+sources of legacy. A lot of its defaults are questionable at best, and often
+need replacing. As a consequence of this, a range of 'better ``Prelude``s' have
+been written, with a range of opinions: while there is a common core, a large
+number of decisions are opinionated in ways more appropriate to the authors of
+said alternatives and their needs than those of other users of said
+alternatives. This means that, when a non-``base`` ``Prelude`` is in scope, it
+often requires familiarity with its specific decisions, in addition to whatever
+cognitive load the current module and its other imports impose. Given that we
+already use an alternative prelude (in tandem with the one from ``base``),
+additional alternatives present an unnecessary cognitive load. Lastly, the 
+dependency footprint of many alternative ``Prelude``s is _highly_ non-trivial; 
+it isn't clear if we need all of this in our dependency tree.
+
+For all of the above reasons, the best choice is 'default to Plutus, with local
+replacements from `base`'.
+
+## Versioning
+
+A project MUST use the [PVP][pvp]. Two, and only two, version numbers MUST be
+used: a major version and a minor version.
+
+### Justification
+
+The [Package Versioning Policy][pvp] is the conventional Haskell versioning
+scheme, adopted by most packages on Hackage. It is clearly described, and even
+automatically verifiable by use of tools like [``policeman``][policeman]. Thus,
+adopting it is both in line with community standards (making it easier to
+remember), and simplifies cases such as Hackage publication or open-sourcing in
+general.
+
+Two version numbers (major and minor) is the minimum allowed by the PVP,
+indicating compilation-breaking and compilation-non-breaking changes
+respectively. As parsimony is best, and more granularity than this isn't
+generally necessary, adopting this model is the right decision.
+
+## Documentation
+
+Every publically-exported definition MUST have a Haddock comment, detailing its
+purpose. If a definition is a function, it SHOULD also have examples of use
+using [Bird tracks][bird-tracks]. The Haddock for a publically-exported
+definition SHOULD also provide an explanation of any caveats, complexities of
+its use, or common issues a user is likely to encounter. 
+
+If the code project is a library, these Haddock comments SHOULD carry an
+[``@since``][haddock-since] annotation, stating what version of the library they
+were introduced in, or the last version where their functionality or type
+signature changed.
+
+For type classes, their laws MUST be documented using a Haddock comment.
+
+### Justification
+
+Code reading is a difficult task, especially when the 'why' rather than the
+'how' of the code needs to be deduced. A good solution to this is documentation,
+especially when this documentation specifies common issues, provides examples of
+use, and generally states the rationale behind the definition.
+
+For libraries, it is often important to inform users what changed in a given
+version, especially where 'major bumps' are concerned. While this would ideally
+be addressed with accurate changelogging, it can be difficult to give proper
+context. ``@since`` annotations provide a granular means to indicate the last
+time a definition changed considerably, allowing someone to quickly determine
+whether a version change affects something they are concerned with.
+
+As stated elsewhere in the document, type classes having laws is critical to our
+ability to use equational reasoning, as well as a clear indication of what
+instances are and aren't permissible. These laws need to be clearly stated, as
+this assists both those seeking to understand the purpose of the type class, and
+also the expected behaviour of its instances.
+
+## Other
+
+Lists SHOULD NOT be field values of types; this extends to ``String``s. Instead,
+``Vector``s (``Text``s) SHOULD be used, unless a more appropriate structure exists. 
+On-chain code, due to a lack of alternatives, is one place lists can be used as
+field values of types.
+
+Partial functions MUST NOT be defined. Partial functions SHOULD NOT be used
+except to ensure that another function is total (and the type system cannot be
+used to prove it). 
+
+Derivations MUST use an explicit [strategy][deriving-strategies]. Thus, the 
+following is wrong:
+
+```haskell
+newtype Foo = Foo (Bar Int)
+    deriving (Eq, Show, Generic, FromJSON, ToJSON, Data, Typeable)
+```
+
+Instead, write it like this:
+
+```haskell
+newtype Foo = Foo (Bar Int)
+    deriving stock (Generic, Data, Typeable)
+    deriving newtype (Eq, Show)
+    deriving anyclass (FromJSON, ToJSON)
+```
+
+Deriving via SHOULD be preferred to newtype derivation, especially where the
+underlying type representation could change significantly.
+
+``type`` SHOULD NOT be used. The only acceptable case is abbreviation of large
+type-level computations. In particular, using ``type`` to create an abstraction
+boundary MUST NOT be done.
+
+Type variables MUST have an explicit ``forall`` scoping it, and all type
+variables MUST have kind signatures explicitly provided. Thus, the following is
+wrong:
+
+```haskell
+data Foo a = Bar | Baz [a]
+
+quux :: (Monoid m) => [m] -> m -> m
+```
+
+Instead, write it like this:
+
+```haskell
+data Foo (a :: Type) = Bar | Baz [a]
+
+quux :: forall (m :: Type) . (Monoid m) => [m] -> m -> m
+```
+
+### Justification
+
+Haskell lists are a large example of the legacy of the language: they (in the
+form of singly linked lists) have played an important role in the development of
+functional programming (and for some 'functional' languages, continue to do so).
+However, from the perspective of data structures, they are suboptimal except for
+_extremely_ specific use cases. In almost any situation involving data (rather
+than control flow), an alternative, better structure exists. Although it is both
+acceptable and efficient to use lists within functions (due to GHC's extensive
+fusion optimizations), from the point of view of field values, they are a poor
+choice from both an efficiency perspective, both in theory _and_ in practice.
+For almost all cases where you would want a list field value, a ``Vector`` field
+value is more appropriate, and in almost all others, some other structure (such
+as a ``Map``) is even better.
+
+Partial functions are runtime bombs waiting to explode. The number of times the
+'impossible' happened, especially in production code, is significant in our
+experience, and most partiality is easily solvable. Allowing the compiler to
+support our efforts, rather than being blind to them, will help us write more
+clear, more robust, and more informative code. Partiality is also an example of
+legacy, and it is legacy of _considerable_ weight. Sometimes, we do need an
+'escape hatch' due to the impossibility of explaining what we want to the
+compiler; this should be the _exception_, not the rule.
+
+Derivations are one of the most useful features of GHC, and extend the
+capabilities of Haskell 2010 considerably. However, with great power comes great
+ambiguity, especially when ``GeneralizedNewtypeDeriving`` is in use. While there
+_is_ an unambiguous choice if no strategy is given, it becomes hard to remember.
+This is especially dire when ``GeneralizedNewtypeDeriving`` combines with
+``DeriveAnyClass`` on a newtype. Explicit strategies give more precise control
+over this, and document the resulting behaviour locally. This reduces the number
+of things we need to remember, and allows more precise control when we need it.
+Lastly, in combination with ``DerivingVia``, considerable boilerplate can be
+saved; in this case, explicit strategies are _mandatory_.
+
+The only exception to the principle above is newtype deriving, which can
+occasionally cause unexpected problems; if we use a newtype derivation, and
+change the underlying type, we get no warning. Since this can affect the effect
+of some type classes drastically, it would be good to have the compiler check
+our consistency.
+
+``type`` is generally a terrible idea in Haskell. You don't create an
+abstraction boundary with it (any operations on the 'underlying type' still work
+over it), and compiler output becomes _very_ inconsistent (sometimes showing the
+``type`` definition, sometimes the underlying type). If your goal is to create
+an abstraction boundary with its own operations, ``newtype`` is both cost-free
+and clearer; if that is _not_ your goal, just use the type you'd otherwise
+rename, since it's equivalent semantically. The only reasonable use of ``type``
+is to hide complex type-level computations, which would otherwise be too long.
+Even this is somewhat questionable, but the questionability comes from the
+type-level computation being hidden, not ``type`` as such.
+
+Type-level programming is mandated in many places by Plutus (including, but not
+limited to, row-polymorphic records and variants from `Data.Row`). This often
+requires use of ``TypeApplications``, which essentially makes not only the type
+variables, but their _order_, part of the API of any definition that uses them.
+While there is an algorithm determining this precisely, something that is
+harmless at the value level (such as re-ordering constraints) could potentially
+serve as an API break. Additionally, this algorithm is a huge source of
+non-local information, and in the presence of a large number of type variables,
+of different kinds, can easily become confusing. Having explicit foralls
+quantifying all type variables makes it clear what the order for these type
+variables is for ``TypeApplications``, and also allows us to choose it
+optimally for our API, rather than relying on what the algorithm would produce.
+This is significantly more convenient, and means less non-local information and
+confusion.
+
+Additionally, type-level programming requires significant use of 'exotic kinds',
+which in our case include ``Constraint -> Type`` and ``Row Type``, to name but a
+few. While GHC can (mostly) infer kind signatures, much the same way as we
+explicitly annotate type signatures as a form of active documentation (and to
+assist the type checker when using type holes), explicitly annotating _kind_
+signatures allows us to be clear to the users where exotic kinds are expected,
+as well as ensuring that we don't make any errors ourselves. This, together with
+explicit foralls, essentially bring the same practices to the kind level as the
+Haskell community already considers to be good at the type level.
+
+# Design practices
+
+## Parse, don't validate
+
+[Boolean blindness][boolean-blindness] SHOULD NOT be used in the design of any
+function or API. Returning more meaningful data SHOULD be the preferred choice.
+The general principle of ['parse, don't validate'][parse-dont-validate] SHOULD
+guide design and implementation.
+
+### Justification
+
+The [description of boolean blindness][boolean-blindness] gives specific reasons why it is a poor
+design choice; additionally, it runs counter to the principle of ['parse, don't
+validate][parse-dont-validate]. While sometimes unavoidable, in many cases, it's
+possible to give back a more meaningful response than 'yes' or 'no, and we
+should endeavour to do this. Designs that avoid boolean blindness are more
+flexible, less bug-prone, and allow the type checker to assist us when writing.
+This, in turn, reduces cognitive load, improves our ability to refactor, and
+means fewer bugs from things the compiler _could_ have checked if a function
+_wasn't_ boolean-blind.
+
+## No multi-parameter type-classes without functional dependencies
+
+Any multi-parameter type class MUST have a functional dependency restricting its
+relation to a one-to-many at most. In cases of true many-to-many relationships,
+type classes MUST NOT be used as a solution to the problem.
+
+### Justification
+
+Multi-parameter type classes allow us to express more complex relationships
+among types; single-parameter type classes effectively permit us to 'subset'
+``Hask`` only. However, multi-parameter type classes make type inference
+_extremely_ flakey, as the global coherence condition can often lead to the
+compiler being unable to determine what instance is sought even if all the type
+parameters are concrete, due to anyone being able to add a new instance at any
+time. This is largely caused by multi-parameter type classes defaulting to
+effectively representing arbitrary many-to-many relations.
+
+When we do not _have_ arbitrary many-to-many relations, multi-parameter type
+classes are useful and convenient. We can indicate this using functional
+dependencies, which inform the type checker that our relationship is not
+arbitrarily many-to-many, but rather many-to-one or even one-to-one. This is a
+standard practice in many libraries (``mtl`` being the most ubiquitous example),
+and allows us the benefits of multi-parameter type classes without making type
+checking confusing and difficult.
+
+In general, many-to-many relationships pose difficult design choices, for which
+type classes are _not_ the correct solution. If a functional dependency _cannot_
+be provided for a type class, it suggests that the current design relies
+inherently on a many-to-many relation, and should be either rethought to
+eliminate it, or be dealt with using a more appropriate means.
+
+## Type classes must have laws
+
+Any type class not imported from an external dependency MUST have laws. These
+laws MUST be documented in a Haddock comment on the type class definition, and
+all instances MUST follow these laws.
+
+### Justification
+
+Type classes are a powerful feature of Haskell, but can also be its most
+confusing. As they allow arbitrary ad-hoc polymorphism, and are globally
+visible, it is important that we limit the confusion this can produce.
+Additionally, type classes without laws inhibit equational reasoning, which is
+one of Haskell's biggest strengths, _especially_ in the presence of what amounts
+to arbitrary ad-hoc polymorphism.
+
+Additionally, type classes with laws allow the construction of _provably_
+correct abstractions above them. This is also a common feature in Haskell,
+ranging from profunctor optics to folds. If we define our own type classes, we
+want to be able to abstract above them with _total_ certainty of correctness.
+Lawless type classes make this difficult to do: compare the number of
+abstractions built on `Functor` or `Traversable` as opposed to `Foldable`.
+
+Thus, type classes having laws provides both ease of understanding and
+additional flexibility.

Subject: [PATCH 068/451] install process work

I have documented the install process up to the point that it works... there are some errors that need to be ironed out the we are having during the installation - There are some work arounds but I want to try to get it working the correct way.
I implemented a new virtual machine and ran through the install process as I wrote this to make sure that everything up until running `make build` worked correctly.
I just saw that @Benjmhart advised that we are keeping everything in this repo and I believe there is also a ticket in with IOHK to solve some of these issues. I will get with Ben and see how he wants me to proceed.

-- [Use Case: NFT](#use-case-nft)
+
+-  [Use Case: Lendex](#use-case-lendex)
+
+-  [Use Case: NFT](#use-case-nft)
 
 ### Prerequisites
 
-- List all dependencies, like `nix` etc.
+- Git 
+- Curl
+- Nix
 
 ### Building, Testing, Use
 
-*Add step by step instructions on how to build, test and use the software.*
-
-1. Clone the repo and run `make` 
-2. ...
+*It is recommended that all current updates to your system be done before installation*
+
+1) ***Install basic dependencies*** 
+
+    `sudo apt install curl`
+    
+    `sudo apt install git`
+
+2) ***Clone Directory***
+
+	Create a directory and clone the project:
+ 
+	`git clone https://github.com/mlabs-haskell/plutus-use-cases.git`
+ 
+3) ***Install Nix***
+  
+
+   1) **Setup Nix**
+	   
+    $ `curl -L https://nixos.org/nix/install | sh`
+
+      - *There is a issue with nix correctly adjusting the PATH in some machines. Please re-start your terminal and make sure Nix is in the path (`nix --version`).  Please see this discussion if you are having this issue:  https://github.com/NixOS/nix/issues/3317*
+
+      - *This is the direct link to the nix download page for reference: https://nixos.org/download.html*
+
+   2) **Set up binary cache** 
+	
+      ***Make sure to set up the IOHK binary cache. If you do not do this, you will end up building GHC, which takes several hours. If you find yourself building GHC, STOP and fix the cache.***
+	
+      To set up the binary cache:
+		
+  * On **non-NixOS** machines:
+		    Create a nix directory and file in the `etc` directory. 
+			
+       1) `sudo mkdir /etc/nix`
+			
+       2) `sudo touch /etc/nix/nix.conf`
+			
+     *Then edit your `nix.conf` file to add:*
+		
+         `substituters        = https://hydra.iohk.io https://iohk.cachix.org https://cache.nixos.org/`
+         `trusted-public-keys = hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ= iohk.cachix.org-1:DpRUyj7h7V830dp/i6Nti+NEO2/nhblbov/8MW7Rqoo= cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=`
+     
+     
+  * On **NixOS** Machines, add the following NixOs options:
+         
+         `nix = {
+          binaryCaches          = [ "https://hydra.iohk.io" "https://iohk.cachix.org" ];`
+         `binaryCachePublicKeys = [ "hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ=" "iohk.cachix.org-1:DpRUyj7h7V830dp/i6Nti+NEO2/nhblbov/8MW7Rqoo=" ];
+          };`
+
+Please see the original documentation at IOHK for reference: -   [How to set up the IOHK binary caches](https://github.com/input-output-hk/plutus/blob/master/README.adoc#iohk-binary-cache)
+
+4) ***Create nix shell***
+Go to the `plutus-use-cases/mlabs` directory
+run the `nix-shell` command:
+
+	$ `nix-shell` 
+	- *(This will take a little while the first time)*

 ## Use Case: Lendex 
 
 ### Description
-*TODO: Small description/summary*
+The Lendex Use Case is based on the Open Source, Non-Custodial Aave Protocol,
+described in the [Aave Protocol
+Whitepaper](https://github.com/aave/aave-protocol/blob/master/docs/Aave_Protocol_Whitepaper_v1_0.pdf).
+The use case can be summaraised as a platform for a decentralised, pool-based,
+loan strategy.
+
+As described in the whitepaper, the model relies on Lenders depositing (Cardano)
+cryptocurrency in a Pool Contract. The same Pool Contract provides a source for
+funds to be borrowed by Borrowes through the placement of a collateral. Loans do
+not need to be individually matched, but rather rely on the pooled funds, the
+amounts borrowed and their respective collateral. The model enables instant
+loans and the interest rate for both borrowers and lenders is decided
+algorithimically. A general description of the interest algorithm is:
+
+  - Borrower's interest is tied to the amount of funds available in the pool at
+    a specific time - with scarcity of funds driving the interest rate up.
+    
+  - Lender's interest rate corresponds to the earn rate, with the algorithm
+    safeguarding a liquidity reserve to guarantee ease of withdrawals at any
+    given time.

 ## Use Case: NFT
 
 ### Description
-*TODO: Small description/summary*
+The core functionality of the Non Fungible Tokens(i.e. NFTs) Use Case revolves
+around minting, sending, receiving NFTs into a Cardano wallet.
+
+NFTs are a digital asset that represents real-world objects. They can be bought
+and sold online, and act as a proof of ownership for the underlying asset they
+are meant to represent. Fungibility is the property of an asset to be
+interchangeable with its equal value in another fungible asset (example: $1 and
+10x $0.10 are interchangeable). Given that real-world objects cannot be replaced
+as easily with equivalent objects is a propert reflected in the nature of NFTs.
+
+For more details on NFT's refer to:
+  - [Forbes: What You Need To Know About NFT's](https://www.forbes.com/advisor/investing/nft-non-fungible-token/)

+# Introduction
+
+This document describes a set of standards for all code under the Plutus Use Cases
+project. It also explains our reasoning for these choices, and acts as a living
+document of our practices for current and future contributors to the project. We
+intend for this document to evolve as our needs change, as well as act as a
+single point of truth for standards.
+
+# Motivation
+
+The desired outcomes from the prescriptions in this document are as follows.
+
+## Increase consistency
+
+Inconsistency is worse than _any_ standard, as it requires us to track a large
+amount of case-specific information. Software development is already a difficult
+task due to the inherent complexities of the problems we seek to solve, as well
+as the inherent complexities foisted upon us by _decades_ of bad historical
+choices we have no control over. For newcomers to a project and old hands alike,
+increased inconsistency translates to developmental friction, resulting in
+wasted time, frustration and ultimately, worse outcomes for the code in
+question.
+
+To avoid putting ourselves into this boat, both currently and in the future, we
+must strive to be _automatically consistent_. Similar things should look
+similar; different things should look different; as much as possible, we must
+pick some rules _and stick to them_; and this has to be clear, explicit and
+well-motivated. This will ultimately benefit us, in both the short and the long
+term. The standards described here, as well as this document itself, is written
+with this foremost in mind.
+
+## Limit non-local information
+
+There is a limited amount of space in a developer's skull; we all have bad days,
+and we forget things or make decisions that, perhaps, may not be ideal at the
+time. Therefore, limiting cognitive load is good for us, as it reduces the
+amount of trouble we can inflict due to said skull limitations. One of the worst
+contributors to cognitive load (after inconsistency) is _non-local information_
+- the requirement to have some understanding beyond the scope of the current
+unit of work. That unit of work can be a data type, a module, or even a whole
+project; in all cases, the more non-local information we require ourselves to
+hold in our minds, the less space that leaves for actually doing the task at
+hand, and the more errors we will introduce as a consequence.
+
+Thus, we must limit the need for non-local information at all possible levels.
+'Magic' of any sort must be avoided; as much locality as possible must be
+present everywhere; needless duplication of effort or result must be avoided.
+Thus, our work must be broken down into discrete, minimal, logical units, which
+can be analyzed, worked on, reviewed and tested in as much isolation as
+possible. This also applies to our external dependencies.
+
+Thus, many of the decisions described here are oriented around limiting the
+amount of non-local knowledge required at all levels of the codebase.
+Additionally, we aim to avoid doing things 'just because we can' in a way that
+would be difficult for other Haskellers to follow, regardless of skill level.
+
+## Minimize impact of legacy
+
+Haskell is a language that is older than some of the people currently writing
+it; parts of its ecosystem are not exempt from it. With age comes legacy, and
+much of it is based on historical decisions which we now know to be problematic
+or wrong. We can't avoid our history, but we can minimize its impact on our
+current work. 
+
+Thus, we aim to codify good practices in this document _as seen today_. We also
+try to avoid obvious 'sharp edges' by proscribing them away in a principled,
+consistent and justifiable manner. 
+
+## Automate away drudgery
+
+As developers, we should use our tools to make ourselves as productive as
+possible. There is no reason for us to do a task if a machine could do it for
+us, especially when this task is something boring or repetitive. We love Haskell
+as a language not least of all for its capability to abstract, to describe, and
+to make fun what other languages make dull or impossible; likewise, our work
+must do the same.
+
+Many of the tool-related proscriptions and requirements in this document are
+driven by a desire to remove boring, repetitive tasks that don't need a human to
+perform. By removing the need for us to think about such things, we can focus on
+those things which _do_ need a human; thus, we get more done, quicker.
+
+# Conventions
+
+The words MUST, SHOULD, MUST NOT, SHOULD NOT and MAY are defined as per [RFC
+2119][rfc-2119].
+
+# Tools
+
+## Compiler warning settings
+
+The following warnings MUST be enabled for all builds of any project, or any
+project component:
+
+* ``-Wall``
+* ``-Wcompat``
+* ``-Wincomplete-uni-patterns``
+* ``-Wredundant-constraints``
+* ``-Werror``
+
+Additionally, ``-Wincomplete-record-updates`` SHOULD be enabled for all builds
+of any project. The only exception is when this warning would be spuriously
+triggered by ``record-dot-preprocessor``, which occurs for definitions like
+this:
+
+```haskell
+data Foo = Bar {
+   baz :: Int,
+   quux :: String
+   } | 
+   Quux
+```
+
+Additionally, ``-Wredundant-constraints`` SHOULD be enabled for all builds of
+any project. Exceptions are allowed when the additional constraints are designed
+to ensure safety, rather than due to reliance on any method.
+
+If a warning from this list is to be disabled, it MUST be disabled in the
+narrowest possible scope; ideally, this SHOULD be a single module.
+
+### Justification
+
+These options are suggested by [Alexis King][alexis-king-options] - the
+justifications for them can be found at the link. These fit well with our
+motivations, and thus, should be used everywhere. The ``-Werror`` ensures that
+warnings _cannot_ be ignored: this means that problems get fixed sooner.
+
+The two permissible exceptions stem from limitations in the record-dot plugin
+(for ``-Wincomplete-record-updates``) and from the way redundant constraints are
+detected; basically, unless a type class method from a constraint is used within
+the body of the definition, or is required by anything called in a transitive
+manner, the constraint is deemed redundant. Mostly, this is accurate, but some
+type-level safety constraints can be deemed redundant as a result of this
+approach. In this case, a limited lowering (per module ideally) of those two
+warnings is acceptable, as they represent workarounds to technical problems,
+rather than issues with the warnings themselves.
+
+## Linting
+
+Every source file MUST be free of warnings as produced by [HLint][hlint], with
+default settings.
+
+### Justification
+
+HLint automates away the detection of many common sources of boilerplate and
+inefficiency. It also describes many useful refactors, which in many cases make
+the code easier to read and understand. As this is fully automatic, it saves
+effort on our part, and ensures consistency across the codebase without us
+having to think about it.
+
+## Code formatting
+
+Every source file MUST be formatted according to [Fourmolu][fourmolu], with the
+following settings (as per its settings file):
+
+* ``indentation: 2``
+* ``comma-style: leading``
+* ``record-brace-space: true``
+* ``indent-wheres: true``
+* ``diff-friendly-import-export: true``
+* ``respectful: true``
+* ``haddock-style: multi-line``
+* ``newlines-between-decls: 1``
+
+Each source code line MUST be at most 100 characters wide, and SHOULD
+be at most 80 characters wide.
+
+### Justification
+
+Consistency is the most important goal of readable codebases. Having a single
+standard, automatically enforced, means that we can be sure that everything will
+look similar, and not have to spend time or mind-space ensuring that our code
+complies. Additionally, as Ormolu is opinionated, anyone familiar with its
+layout will find our code familiar, which eases the learning curve.
+
+Lines wider than 80 characters become difficult to read, especially when viewed
+on a split screen. Sometimes, we can't avoid longer lines (especially with more
+descriptive identifiers), but a line length of over 100 characters becomes
+difficult to read even without a split screen. We don't _enforce_ a maximum of
+80 characters for this exact reason; some judgment is allowed.
+
+# Code practices
+
+## Naming
+
+camelCase MUST be used for all non-type, non-data-constructor names; otherwise,
+TitleCase MUST be used. Acronyms used as part of a naming identifier (such as 
+'JSON', 'API', etc) SHOULD be downcased; thus ``repairJson`` and
+``fromHttpService`` are correct. Exceptions are allowed for external libraries
+(Aeson's ``parseJSON`` for example).
+
+### Justification
+
+camelCase for non-type, non-data-constructor names is a long-standing convention
+in Haskell (in fact, HLint checks for it); TitleCase for type names or data
+constructors is _mandatory_. Obeying such conventions reduces cognitive load, as
+it is common practice among the entire Haskell ecosystem. There is no particular
+standard regarding acronym casing: examples of always upcasing exist (Aeson) as
+well as examples of downcasing (``http-api-data``). One choice for consistency
+(or as much as is possible) should be made however.
+
+## Modules
+
+All publically facing modules (namely, those which are not listed in
+``other-modules`` in the Cabal file) MUST have explicit export lists.
+
+All modules MUST use one of the following conventions for imports:
+
+* ``import Foo (Baz, Bar, quux)``
+* ``import qualified Foo as F``
+
+Data types from qualified-imported modules SHOULD be imported unqualified by
+themselves:
+
+```haskell
+import Data.Vector (Vector)
+import qualified Data.Vector as Vector
+```
+
+The main exception is if such an import would cause a name clash:
+
+```haskell
+-- no way to import both of these without clashing the Vector type name
+import qualified Data.Vector as Vector
+import qualified Data.Vector.Storable as VStorable
+```
+
+The _sole_ exception is a 'hiding import' to replace part of the functionality
+of ``Prelude``:
+
+```haskell
+-- replace the String-based readFile with a Text-based one
+import Prelude hiding (readFile)
+import Data.Text.IO (readFile)
+```
+
+Data constructors SHOULD be imported individually. For example, given the
+following data type declaration:
+
+```haskell
+module Quux where
+
+data Foo = Bar Int | Baz
+```
+
+Its corresponding import should be:
+
+```haskell
+import Quux (Foo, Bar, Baz)
+```
+
+For type class methods, the type class and its methods MUST be imported
+as so:
+
+```haskell
+import Data.Aeson (FromJSON (fromJSON))
+```
+
+Qualified imports SHOULD use the entire module name (that is, the last component
+of its hierarchical name) as the prefix. For example:
+
+```haskell
+import qualified Data.Vector as Vector
+```
+
+Exceptions are granted when:
+
+* The import would cause a name clash anyway (such as different ``vector``
+  modules); or
+* We have to import a data type qualified as well.
+
+Qualified imports of multiple modules MUST NOT be imported under the same name.
+Thus, the following is wrong:
+
+```haskell
+import qualified Foo.Bar as Baz
+import qualified Foo.Quux as Baz
+```
+
+### Justification
+
+Explicit export lists are an immediate, clear and obvious indication of what
+publically visible interface a module provides. It gives us stability guarantees
+(namely, we know we can change things that aren't exported and not break
+downstream code at compile time), and tells us where to go looking first when
+inspecting or learning the module. Additionally, it means there is less chance
+that implementation details 'leak' out of the module due to errors on the part
+of developers, especially new developers.
+
+One of the biggest challenges for modules which depend on other modules
+(especially ones that come from the project, rather than an external library) is
+knowing where a given identifier's definition can be found. Having explicit
+imports of the form described helps make this search as straightforward as
+possible. This also limits cognitive load when examining the sources (if we
+don't import something, we don't need to care about it in general). Lastly,
+being explicit avoids stealing too many useful names.
+
+In general, type names occur far more often in code than function calls: we have
+to use a type name every time we write a type signature, but it's unlikely we
+use only one function that operates on said type. Thus, we want to reduce the
+amount of extra noise needed to write a type name if possible. Additionally,
+name clashes from function names are far more likely than name clashes from type
+names: consider the number of types on which a ``size`` function makes sense.
+Thus, importing type names unqualified, even if the rest of the module is
+qualified, is good practice, and saves on a lot of prefixing.
+
+## Plutus module import naming conventions
+
+In addition to the general module import rules, we follow some conventions 
+on how we import the Plutus API modules, allowing for some flexibility 
+depending on the needs of a particular module.
+
+Modules under the names `Plutus`, `Ledger` and `Plutus.V1.Ledger` SHOULD 
+be imported qualified with their module name, as per the general module standards. 
+An exception to this is `Plutus.V1.Ledger.Api`, where the `Ledger` name is preferred.
+
+Some other exceptions to this are allowed where it may be more convenient to 
+avoid longer qualified names.
+
+For example:
+
+```haskell
+import Plutus.V1.Ledger.Slot qualified as Slot
+import Plutus.V1.Ledger.Tx qualified as Tx
+import Plutus.V1.Ledger.Api qualified as Ledger
+import Ledger.Oracle qualified as Oracle
+import Plutus.Contract qualified as Contract
+```
+
+In some cases it may be justified to use a shortened module name:
+
+```haskell
+import Plutus.V1.Ledger.AddressMap qualified as AddrMap
+```
+
+Modules under `PlutusTx` that are extensions to `PlutusTx.Prelude` MAY be 
+imported unqualified when it is reasonable to do so. 
+
+The `Plutus.V1.Ledger.Api` module SHOULD be avoided in favour of more 
+specific modules where possible. For example, we should avoid:
+
+```haskell
+import Plutus.V1.Ledger.Api qualified as Ledger (ValidatorHash)
+```
+
+In favour of:
+
+```haskell
+import Plutus.V1.Ledger.Scripts qualified as Scripts (ValidatorHash)
+```
+
+### Justification
+
+The Plutus API modules can be confusing, with numerous modules involved, many 
+exporting the same items. Consistent qualified names help ease this problem, 
+and decrease ambiguity about where imported items come from.
+
+## LANGUAGE pragmata
+
+The following pragmata MUST be enabled at project level (that is, in
+``package.yaml``):
+
+* ``BangPatterns``
+* ``BinaryLiterals``
+* ``ConstraintKinds``
+* ``DataKinds``
+* ``DeriveFunctor``
+* ``DeriveGeneric``
+* ``DeriveTraversable``
+* ``DerivingStrategies``
+* ``DuplicateRecordFields``
+* ``EmptyCase``
+* ``FlexibleContexts``
+* ``FlexibleInstances``
+* ``GADTs``
+* ``GeneralizedNewtypeDeriving``
+* ``HexFloatLiterals``
+* ``InstanceSigs``
+* ``ImportQualifiedPost``
+* ``KindSignatures``
+* ``LambdaCase``
+* ``MultiParamTypeClasses``
+* ``NoImplicitPrelude``
+* ``NumericUnderscores``
+* ``OverloadedStrings``
+* ``StandaloneDeriving``
+* ``TupleSections``
+* ``TypeApplications``
+* ``TypeOperators``
+* ``TypeSynonymInstances``
+* ``UndecidableInstances``
+
+Any other LANGUAGE pragmata MUST be enabled per-file. All language pragmata MUST
+be at the top of the source file, written as ``{-# LANGUAGE PragmaName #-}``.
+
+Furthermore, the following pragmata MUST NOT be used, or enabled, anywhere:
+
+* ``DeriveDataTypeable``
+* ``DeriveFoldable``
+* ``PartialTypeSignatures``
+* ``PostfixOperators``
+
+### Justification
+
+``DataKinds``, ``DuplicateRecordFields``, ``GADTs``, ``TypeApplications``,
+``TypeSynonymInstances`` and ``UndecidableInstances`` are needed globally to use
+the GHC plugin from ``record-dot-preprocessor``. While some of these extensions
+are undesirable to use globally, we end up needing them anyway, so we can't
+really avoid this.
+
+``BangPatterns`` are a much more convenient way to force evaluation than
+repeatedly using `seq`. Furthemore, they're not confusing, and are considered
+ubiquitous enough for ``GHC2021``. Having them on by default simplifies a lot of
+performance tuning work, and they don't really need signposting.
+
+``BinaryLiterals``, ``HexFloatLiterals`` and ``NumericUnderscores`` all simulate
+features that are found in many other programming languages, and that are
+extremely convenient in a range of settings, ranging from dealing with large
+numbers to bit-twiddling. If anything, it is more surprising and annoying when
+these _aren't_ enabled, and should really be part of Haskell syntax anyway.
+Enabling this project-wide actually encourages better practice and readability.
+
+The kind ``Constraint`` is not in Haskell2010, and thus, isn't recognized by
+default. While working with constraints as first-class objects isn't needed
+often, this extension effectively exists because Haskell2010 lacks exotic kinds
+altogether. Since we require explicit kind signatures (and foralls) for all type
+variables, this needs to be enabled as well. There is no harm in enabling this
+globally, as other rich kinds (such as ``Symbol`` or ``Nat``) don't require an
+extension for their use, and this doesn't change any behaviour (``Constraint``
+exists whether you enable this extension or not, as do 'exotic kinds' in
+general).
+
+``DerivingStrategies`` is good practice (and in fact, is mandated by this
+document); it avoids ambiguities between ``GeneralizedNewtypeDeriving`` and
+``DeriveAnyClass``, allows considerable boilerplate savings through use of
+``DerivingVia``, and makes the intention of the derivation clear on immediate
+reading, reducing the amount of non-local information about derivation
+priorities that we have to retain. ``DeriveFunctor`` and
+``GeneralizedNewtypeDeriving`` are both obvious and useful extensions to the
+auto-derivation systems available in GHC. Both of these have only one correct
+derivation (the former given by [parametricity
+guarantees][functor-parametricity], the latter by the fact that a newtype only
+wraps a single value). As there is no chance of unexpected behaviour by these,
+no possible behaviour variation, and that they're key to supporting both the
+``stock`` and ``newtype`` deriving stratgies, having these on by default removes
+considerable tedium and line noise from our code. A good example are newtype
+wrappers around monadic stacks:
+
+```haskell
+newtype FooM a = FooM (ReaderT Int (StateT Text IO) a)
+  deriving newtype (
+    Functor, 
+    Applicative, 
+    Monad, 
+    MonadReader Int, 
+    MonadState Text, 
+    MonadIO
+    )
+```
+
+Deriving ``Traversable`` is a little tricky. While ``Traversable`` is lawful
+(though not to the degree ``Functor`` is, permitting multiple implementations in
+many cases), deriving it is complicated by issues of role assignation for
+higher-kinded type variables and the fact that you can't ``coerce`` through a
+``Functor``. These are arguably implementation issues, but repairing this
+situation requires cardinal changes to ``Functor``, which is unlikely to ever
+happen. Even newtype or via derivations of ``Traversable`` are mostly
+impossible; thus, we must have special support from GHC, which
+``DeriveTraversable`` enables. This is a very historically-motivated
+inconsistency, and should really not exist at all. While this only papers over
+the problem (as even with this extension on, only stock derivations become
+possible), it at least means that it can be done at all. Having it enabled
+globally makes this inconsistency slightly less visible, and is completely safe.
+
+While GHC ``Generic``s are far from problem-free, many parts of the Haskell
+ecosystem require ``Generic``, either as such (c.f. ``beam-core``) or for
+convenience (c.f ``aeson``, ``hashable``). Additionally, several core parts of
+Plutus (including ``ToSchema``) are driven by ``Generic``. The derivation is
+trivial in most cases, and having to enable an extension for it is quite
+annoying. Since no direct harm is done by doing this, and use of ``Generic`` is
+already signposted clearly (and is mostly invisible), having this on globally
+poses no problems.
+
+``EmptyCase`` not being on by default is an inconsistency of Haskell 2010, as
+the report allows us to define an empty data type, but without this extension,
+we cannot exhaustively pattern match on it. This should be the default behaviour
+for reasons of symmetry.
+
+``FlexibleContexts`` and ``FlexibleInstances`` paper over a major deficiency of
+Haskell2010, which in general isn't well-motivated. There is no real reason to
+restrict type arguments to variables in either type class instances or type
+signatures: the reasons for this choice in Haskell2010 are entirely for the
+convenience of the implementation. It produces no ambiguities, and in many ways,
+the fact this _isn't_ the default is more surprising than anything.
+Additionally, many core libraries rely on one, or both, of these extensions
+being enabled (``mtl`` is the most obvious example, but there are many others).
+Thus, even for popularity and compatibility reasons, these should be on by
+default.
+
+``InstanceSigs`` are harmless by default, and introduce no complications. Their
+not being default is strange. ``ImportQualifiedPost`` is already a convention 
+of this project, and helps with formatting of imports. 
+
+``KindSignatures`` become extremely useful in any setting where 'exotic kinds'
+(meaning, anything which isn't `Type` or `Type -> Type` or similar) are
+commonplace; much like type signatures clarify expectations and serve as active
+documentation (even where GHC can infer them), explicit kind signatures serve
+the same purpose 'one level up'. When combined with the requirement to provide
+explicit foralls for type variables defined in this document, they simplify the
+usage of 'exotic kinds' and provide additional help from both the type checker
+and the code. Since this project is Plutus-based, we use 'exotic kinds'
+extensively, especially in row-polymorphic records; thus, in our case, this is
+especially important. This also serves as justification for
+`ScopedTypeVariables`, as well as ironing out a weird behaviour where in cases
+such as 
+
+```haskell
+foo :: a -> b
+foo = bar . baz
+   where
+      bar :: String -> b
+      bar = ...
+      baz :: a -> String
+      baz = ...
+```
+
+cause GHC to produce _fresh_ type variables in each ``where``-bind. This is
+confusing and makes little sense - if the user wanted a fresh variable, they
+would name it that way. What's worse is that the type checker emits an error
+that makes little sense (except to those who have learned to look for this
+error), creating even more confusion, especially in cases where the type
+variable is constrained:
+
+```haskell
+foo :: (Monoid m) => m -> String
+foo = bar . baz
+   where
+      baz :: m -> Int
+      baz = ... -- this has no idea that m is a Monoid, since m is fresh!
+```
+
+``LambdaCase`` reduces a lot of code in the common case of analysis of sum
+types. Without it, we are forced to either write a dummy ``case`` argument:
+
+```haskell
+foo s = case s of
+-- rest of code here
+```
+
+Or alternatively, we need multiple heads:
+
+```haskell
+foo Bar = -- rest of code
+foo (Baz x y) = -- rest of code
+-- etc
+```
+
+``LambdaCase`` is shorter than both of these, and avoids us having to bind
+variables, only to pattern match them away immediately. It is convenient, clear
+from context, and really should be part of the language to begin with.
+
+``MultiParamTypeClasses`` are required for a large number of standard Haskell
+libraries, including ``mtl`` and ``vector``, and in many situations. Almost any
+project of non-trivial size must have this extension enabled somewhere, and if
+the code makes significant use of ``mtl``-style monad transformers or defines
+anything non-trivial for ``vector``, it must use it. Additionally, it arguably
+lifts a purely implementation-driven decision of the Haskell 2010 language, much
+like ``FlexibleContexts`` and ``FlexibleInstances``. Lastly, although it can
+introduce ambiguity into type checking, it only applies when we want to define
+our own multi-parameter type classes, which is rarely necessary. Enabling it
+globally is thus safe and convenient.
+
+Based on the recommendations of this document (driven by the needs of the
+project and the fact it's cardinally connected with Plutus),
+``NoImplicitPrelude`` is required to allow us to default to the Plutus prelude
+instead of the one from ``base``.
+
+``OverloadedStrings`` deals with the problem that ``String`` is a suboptimal
+choice of string representation for basically _any_ problem, with the general
+recommendation being to use ``Text`` instead. It is not, however, without its
+problems: 
+
+* ``ByteString``s are treated as ASCII strings by their ``IsString`` instance;
+* Overly polymorphic behaviour of many functions (especially in the presence of
+  type classes) forces extra type signatures;
+
+These are usually caused not by the extension itself, but by other libraries and
+their implementations of either ``IsString`` or overly polymorphic use of type
+classes without appropriate laws (Aeson's ``KeyValue`` is a particularly
+egregious offender here). The convenience of this extension in the presence of
+literals, and the fact that our use cases mostly covers ``Text``, makes it worth
+using by default.
+
+``StandaloneDeriving`` is mostly needed for GADTs, or situations where complex
+type-level computations drive type class instances, requiring users to specify
+constraints manually. This can pose some difficulties syntactically (such as
+with deriving strategies), but isn't a problem in and of itself, as it doesn't
+really change how the language works. Having this enabled globally is not
+problematic.
+
+``TupleSections`` smooths out an oddity in the syntax of Haskell 2010 regarding
+partial application of tuple constructors. Given a function like ``foo :: Int -> String ->
+Bar``, we accept it as natural that we can write ``foo 10`` to get a function of
+type ``String -> Bar``. However, by default, this logic doesn't apply to tuple
+constructors. As special cases are annoying to keep track of, and in this case,
+serve no purpose, as well as being clear from their consistent use, this should
+also be enabled by default; it's not clear why it isn't already.
+
+``TypeOperators`` is practically a necessity when dealing with type-level
+programming seriously. Much how infix data constructors are extremely useful
+(and sometimes clearer than their prefix forms), infix _type_ constructors serve
+a similar functionality. Additionally, Plutus relies on operators at the type
+level significantly - for example, it's not really possible to define a
+row-polymorphic record or variant without them. Having to enable this almost
+everywhere is a needless chore, and having type constructors behaving
+differently to data constructors here is a needless source of inconsistency.
+
+We exclude ``DeriveDataTypeable``, as ``Data`` is a strictly-worse legacy
+version of ``Generic``, and ``Typeable`` no longer needs deriving for anything
+anyway. The only reason to derive either of these is for compatibility with
+legacy libraries, which we don't have any of, and the number of which shrinks
+every year. If we're using this extension at all, it's probably a mistake.
+
+``Foldable`` is possibly the most widely-used lawless type class. Its only laws
+are about self-consistency (such as agreement between ``foldMap`` and
+``foldr``), but unlike something like ``Functor``, ``Foldable`` doesn't have any
+laws specifying its behaviour outside of 'it compiles'. As a result, even if we
+accept its usefulness (a debatable position in itself), there are large numbers
+of possible implementations that could be deemed 'valid'. The approach taken by
+``DeriveFoldable`` is _one_ such approach, but this requires knowing its
+derivation algorithm, and may well not be something you need. Unlike a
+``Functor`` derivation (whose meaning is obvious), a ``Foldable`` one is
+anything but, and requires referencing a lot of non-local information to
+determine how it will behave (especially for the 'richer' ``Foldable``, with
+many additional methods). If you need a ``Foldable`` instance, you will either
+newtype or via-derive it (which doesn't need this extension anyway), or you'll
+write your own (which _also_ doesn't need this extension). Enabling this
+encourages bad practices, is confusing, and ultimately doesn't really benefit
+anything.
+
+``PartialTypeSignatures`` is a misfeature. Allowing leaving in type holes (to be
+filled by GHC's inference algorithm) is an anti-pattern for the same reason that
+not providing top-level signatures: while it's possible (mostly) for GHC to
+infer signatures, we lose considerable clarity and active documentation by doing
+so, in return for (quite minor) convenience. While the use of typed holes during
+development is a good practice, they should not remain in final code. Given that
+Plutus projects require us to do some fairly advanced type-level programming
+(where inference often _fails_), this extension can often provide totally
+incorrect results due to GHC's 'best-effort' attempts at type checking. There is
+no reason to leave behind typed holes instead of filling them in, and we
+shouldn't encourage this.
+
+``PostfixOperators`` are arguably a misfeature. Infix operators already require
+a range of special cases to support properly (what symbols create an infix
+operator, importing them at the value and type level, etc), which postfix
+operators make _worse_. Furthermore, they are seldom, if ever, used, and
+typically aren't worth the trouble. Haskell is not Forth, none of our
+dependencies rely on postfix operators, and defining our own creates more
+problems than it solves.
+
+## ``record-dot-preprocessor``
+
+The GHC plugin from ``record-dot-preprocessor`` SHOULD be enabled globally. 
+
+### Justification
+
+Haskell records are documentedly and justifiably subpar: the [original issue for
+the record dot preprocessor extension][rdp-issue] provides a good summary of the
+reasons. While a range of extensions (including ``DuplicateRecordFields``,
+``DisambiguateRecordFields``, ``NamedFieldPuns``, and many others) have been
+proposed, and accepted, to mitigate the situation, the reality is that, even
+with them in place, use of records in Haskell is considerably more difficult,
+and less flexible, than in any other language in widespread use today. The
+proposal described in the previous link provides a solution which is familiar to
+users of most other languages, and addresses the fundamental issue that makes
+Haskell records so awkward.
+
+While the proposal for the record dot syntax that this preprocessor enables is
+coming, it's not available in the current version of Haskell used by Plutus (and
+thus, transitively, by us). Additionally, the earliest this will be available is
+GHC 9.2, and given that our dependencies must support this version too, it'll be
+considerable time before we can get its benefits. The preprocessor gives us
+these benefits immediately, at some dependency cost. While it's not a perfect
+process, as it involves enabling several questionable extensions, and can
+require disabling an important warning, it significantly reduces issues with
+record use, making it worthwhile. Additionally, when GHC 9.2 becomes usable, we
+can upgrade to it seamlessly.
+
+## Prelude
+
+The ``PlutusTx.Prelude`` MUST be used. A 'hiding import' to remove functionality
+we want to replace SHOULD be used when necessary. If functionality from the
+``Prelude`` in ``base`` is needed, it SHOULD be imported qualified. Other
+preludes MUST NOT be used.
+
+### Justification
+
+As this is primarily a Plutus project, we are in some ways limited by what
+Plutus requires (and provides). Especially for on-chain code, the Plutus prelude
+is the one we need to use, and therefore, its use should be as friction-free as
+possible. As many modules may contain a mix of off-chain and on-chain code, we
+also want to make impendance mismatches as limited as possible.
+
+By the very nature of this project, we can assume a familiarity (or at least,
+the goal of such) with Plutus stuff. Additionally, _every_ Haskell developer is
+familiar with the ``Prelude`` from ``base``. Thus, any replacements of the
+Plutus prelude functionality with the ``base`` prelude should be clearly
+indicated locally.
+
+Haskell is a 30-year-old language, and the ``Prelude`` is one of its biggest
+sources of legacy. A lot of its defaults are questionable at best, and often
+need replacing. As a consequence of this, a range of 'better ``Prelude``s' have
+been written, with a range of opinions: while there is a common core, a large
+number of decisions are opinionated in ways more appropriate to the authors of
+said alternatives and their needs than those of other users of said
+alternatives. This means that, when a non-``base`` ``Prelude`` is in scope, it
+often requires familiarity with its specific decisions, in addition to whatever
+cognitive load the current module and its other imports impose. Given that we
+already use an alternative prelude (in tandem with the one from ``base``),
+additional alternatives present an unnecessary cognitive load. Lastly, the 
+dependency footprint of many alternative ``Prelude``s is _highly_ non-trivial; 
+it isn't clear if we need all of this in our dependency tree.
+
+For all of the above reasons, the best choice is 'default to Plutus, with local
+replacements from `base`'.
+
+## Versioning
+
+A project MUST use the [PVP][pvp]. Two, and only two, version numbers MUST be
+used: a major version and a minor version.
+
+### Justification
+
+The [Package Versioning Policy][pvp] is the conventional Haskell versioning
+scheme, adopted by most packages on Hackage. It is clearly described, and even
+automatically verifiable by use of tools like [``policeman``][policeman]. Thus,
+adopting it is both in line with community standards (making it easier to
+remember), and simplifies cases such as Hackage publication or open-sourcing in
+general.
+
+Two version numbers (major and minor) is the minimum allowed by the PVP,
+indicating compilation-breaking and compilation-non-breaking changes
+respectively. As parsimony is best, and more granularity than this isn't
+generally necessary, adopting this model is the right decision.
+
+## Documentation
+
+Every publically-exported definition MUST have a Haddock comment, detailing its
+purpose. If a definition is a function, it SHOULD also have examples of use
+using [Bird tracks][bird-tracks]. The Haddock for a publically-exported
+definition SHOULD also provide an explanation of any caveats, complexities of
+its use, or common issues a user is likely to encounter. 
+
+If the code project is a library, these Haddock comments SHOULD carry an
+[``@since``][haddock-since] annotation, stating what version of the library they
+were introduced in, or the last version where their functionality or type
+signature changed.
+
+For type classes, their laws MUST be documented using a Haddock comment.
+
+### Justification
+
+Code reading is a difficult task, especially when the 'why' rather than the
+'how' of the code needs to be deduced. A good solution to this is documentation,
+especially when this documentation specifies common issues, provides examples of
+use, and generally states the rationale behind the definition.
+
+For libraries, it is often important to inform users what changed in a given
+version, especially where 'major bumps' are concerned. While this would ideally
+be addressed with accurate changelogging, it can be difficult to give proper
+context. ``@since`` annotations provide a granular means to indicate the last
+time a definition changed considerably, allowing someone to quickly determine
+whether a version change affects something they are concerned with.
+
+As stated elsewhere in the document, type classes having laws is critical to our
+ability to use equational reasoning, as well as a clear indication of what
+instances are and aren't permissible. These laws need to be clearly stated, as
+this assists both those seeking to understand the purpose of the type class, and
+also the expected behaviour of its instances.
+
+## Other
+
+Lists SHOULD NOT be field values of types; this extends to ``String``s. Instead,
+``Vector``s (``Text``s) SHOULD be used, unless a more appropriate structure exists. 
+On-chain code, due to a lack of alternatives, is one place lists can be used as
+field values of types.
+
+Partial functions MUST NOT be defined. Partial functions SHOULD NOT be used
+except to ensure that another function is total (and the type system cannot be
+used to prove it). 
+
+Derivations MUST use an explicit [strategy][deriving-strategies]. Thus, the 
+following is wrong:
+
+```haskell
+newtype Foo = Foo (Bar Int)
+    deriving (Eq, Show, Generic, FromJSON, ToJSON, Data, Typeable)
+```
+
+Instead, write it like this:
+
+```haskell
+newtype Foo = Foo (Bar Int)
+    deriving stock (Generic, Data, Typeable)
+    deriving newtype (Eq, Show)
+    deriving anyclass (FromJSON, ToJSON)
+```
+
+Deriving via SHOULD be preferred to newtype derivation, especially where the
+underlying type representation could change significantly.
+
+``type`` SHOULD NOT be used. The only acceptable case is abbreviation of large
+type-level computations. In particular, using ``type`` to create an abstraction
+boundary MUST NOT be done.
+
+Type variables MUST have an explicit ``forall`` scoping it, and all type
+variables MUST have kind signatures explicitly provided. Thus, the following is
+wrong:
+
+```haskell
+data Foo a = Bar | Baz [a]
+
+quux :: (Monoid m) => [m] -> m -> m
+```
+
+Instead, write it like this:
+
+```haskell
+data Foo (a :: Type) = Bar | Baz [a]
+
+quux :: forall (m :: Type) . (Monoid m) => [m] -> m -> m
+```
+
+`where`-bindings MUST have type signatures.
+
+### Justification
+
+Haskell lists are a large example of the legacy of the language: they (in the
+form of singly linked lists) have played an important role in the development of
+functional programming (and for some 'functional' languages, continue to do so).
+However, from the perspective of data structures, they are suboptimal except for
+_extremely_ specific use cases. In almost any situation involving data (rather
+than control flow), an alternative, better structure exists. Although it is both
+acceptable and efficient to use lists within functions (due to GHC's extensive
+fusion optimizations), from the point of view of field values, they are a poor
+choice from both an efficiency perspective, both in theory _and_ in practice.
+For almost all cases where you would want a list field value, a ``Vector`` field
+value is more appropriate, and in almost all others, some other structure (such
+as a ``Map``) is even better. We make a named exception for on-chain code, as no
+alternatives presently exist.
+
+Partial functions are runtime bombs waiting to explode. The number of times the
+'impossible' happened, especially in production code, is significant in our
+experience, and most partiality is easily solvable. Allowing the compiler to
+support our efforts, rather than being blind to them, will help us write more
+clear, more robust, and more informative code. Partiality is also an example of
+legacy, and it is legacy of _considerable_ weight. Sometimes, we do need an
+'escape hatch' due to the impossibility of explaining what we want to the
+compiler; this should be the _exception_, not the rule.
+
+Derivations are one of the most useful features of GHC, and extend the
+capabilities of Haskell 2010 considerably. However, with great power comes great
+ambiguity, especially when ``GeneralizedNewtypeDeriving`` is in use. While there
+_is_ an unambiguous choice if no strategy is given, it becomes hard to remember.
+This is especially dire when ``GeneralizedNewtypeDeriving`` combines with
+``DeriveAnyClass`` on a newtype. Explicit strategies give more precise control
+over this, and document the resulting behaviour locally. This reduces the number
+of things we need to remember, and allows more precise control when we need it.
+Lastly, in combination with ``DerivingVia``, considerable boilerplate can be
+saved; in this case, explicit strategies are _mandatory_.
+
+The only exception to the principle above is newtype deriving, which can
+occasionally cause unexpected problems; if we use a newtype derivation, and
+change the underlying type, we get no warning. Since this can affect the effect
+of some type classes drastically, it would be good to have the compiler check
+our consistency.
+
+``type`` is generally a terrible idea in Haskell. You don't create an
+abstraction boundary with it (any operations on the 'underlying type' still work
+over it), and compiler output becomes _very_ inconsistent (sometimes showing the
+``type`` definition, sometimes the underlying type). If your goal is to create
+an abstraction boundary with its own operations, ``newtype`` is both cost-free
+and clearer; if that is _not_ your goal, just use the type you'd otherwise
+rename, since it's equivalent semantically. The only reasonable use of ``type``
+is to hide complex type-level computations, which would otherwise be too long.
+Even this is somewhat questionable, but the questionability comes from the
+type-level computation being hidden, not ``type`` as such.
+
+Type-level programming is mandated in many places by Plutus (including, but not
+limited to, row-polymorphic records and variants from `Data.Row`). This often
+requires use of ``TypeApplications``, which essentially makes not only the type
+variables, but their _order_, part of the API of any definition that uses them.
+While there is an algorithm determining this precisely, something that is
+harmless at the value level (such as re-ordering constraints) could potentially
+serve as an API break. Additionally, this algorithm is a huge source of
+non-local information, and in the presence of a large number of type variables,
+of different kinds, can easily become confusing. Having explicit foralls
+quantifying all type variables makes it clear what the order for these type
+variables is for ``TypeApplications``, and also allows us to choose it
+optimally for our API, rather than relying on what the algorithm would produce.
+This is significantly more convenient, and means less non-local information and
+confusion.
+
+Additionally, type-level programming requires significant use of 'exotic kinds',
+which in our case include ``Constraint -> Type`` and ``Row Type``, to name but a
+few. While GHC can (mostly) infer kind signatures, much the same way as we
+explicitly annotate type signatures as a form of active documentation (and to
+assist the type checker when using type holes), explicitly annotating _kind_
+signatures allows us to be clear to the users where exotic kinds are expected,
+as well as ensuring that we don't make any errors ourselves. This, together with
+explicit foralls, essentially bring the same practices to the kind level as the
+Haskell community already considers to be good at the type level.
+
+`where` bindings are quite common in idiomatic Haskell, and quite often contain
+non-trivial logic. They're also a common refactoring, and 'hole-driven
+development' tool, where you create a hole to be filled with a `where`-bound
+definition. Even in these cases, having an explicit signature on
+`where`-bindings helps: during development, you can use typed holes inside the
+`where`-binding with useful information (absent a signature, you'll get
+nothing), and it makes the code much easier to understand, especially if the
+`where`-binding is complex. It's also advantageous when 'promoting'
+`where`-binds to full top-level definitions, as the signature is already there.
+Since we need to do considerable type-level programming as part of Plutus, this
+becomes even more important, as GHC's type inference algorithm can often fail in
+those cases on `where`-bindings, which will sometimes fail to derive, giving a
+very strange error message, which would need a signature to solve anyway. By
+making this practice proactive, we are decreasing confusion, as well as
+increasing readability. While in theory, this standard should extend to
+`let`-bindings as well, these are much rarer, and can be given signatures with
+`::` if `ScopedTypeVariables` is on (which it is for us by default) if needed.
+
+# Design practices
+
+## Parse, don't validate
+
+[Boolean blindness][boolean-blindness] SHOULD NOT be used in the design of any
+function or API. Returning more meaningful data SHOULD be the preferred choice.
+The general principle of ['parse, don't validate'][parse-dont-validate] SHOULD
+guide design and implementation.
+
+### Justification
+
+The [description of boolean blindness][boolean-blindness] gives specific reasons why it is a poor
+design choice; additionally, it runs counter to the principle of ['parse, don't
+validate][parse-dont-validate]. While sometimes unavoidable, in many cases, it's
+possible to give back a more meaningful response than 'yes' or 'no, and we
+should endeavour to do this. Designs that avoid boolean blindness are more
+flexible, less bug-prone, and allow the type checker to assist us when writing.
+This, in turn, reduces cognitive load, improves our ability to refactor, and
+means fewer bugs from things the compiler _could_ have checked if a function
+_wasn't_ boolean-blind.
+
+## No multi-parameter type-classes without functional dependencies
+
+Any multi-parameter type class MUST have a functional dependency restricting its
+relation to a one-to-many at most. In cases of true many-to-many relationships,
+type classes MUST NOT be used as a solution to the problem.
+
+### Justification
+
+Multi-parameter type classes allow us to express more complex relationships
+among types; single-parameter type classes effectively permit us to 'subset'
+``Hask`` only. However, multi-parameter type classes make type inference
+_extremely_ flakey, as the global coherence condition can often lead to the
+compiler being unable to determine what instance is sought even if all the type
+parameters are concrete, due to anyone being able to add a new instance at any
+time. This is largely caused by multi-parameter type classes defaulting to
+effectively representing arbitrary many-to-many relations.
+
+When we do not _have_ arbitrary many-to-many relations, multi-parameter type
+classes are useful and convenient. We can indicate this using functional
+dependencies, which inform the type checker that our relationship is not
+arbitrarily many-to-many, but rather many-to-one or even one-to-one. This is a
+standard practice in many libraries (``mtl`` being the most ubiquitous example),
+and allows us the benefits of multi-parameter type classes without making type
+checking confusing and difficult.
+
+In general, many-to-many relationships pose difficult design choices, for which
+type classes are _not_ the correct solution. If a functional dependency _cannot_
+be provided for a type class, it suggests that the current design relies
+inherently on a many-to-many relation, and should be either rethought to
+eliminate it, or be dealt with using a more appropriate means.
+
+## Type classes must have laws
+
+Any type class not imported from an external dependency MUST have laws. These
+laws MUST be documented in a Haddock comment on the type class definition, and
+all instances MUST follow these laws.
+
+### Justification
+
+Type classes are a powerful feature of Haskell, but can also be its most
+confusing. As they allow arbitrary ad-hoc polymorphism, and are globally
+visible, it is important that we limit the confusion this can produce.
+Additionally, type classes without laws inhibit equational reasoning, which is
+one of Haskell's biggest strengths, _especially_ in the presence of what amounts
+to arbitrary ad-hoc polymorphism.
+
+Additionally, type classes with laws allow the construction of _provably_
+correct abstractions above them. This is also a common feature in Haskell,
+ranging from profunctor optics to folds. If we define our own type classes, we
+want to be able to abstract above them with _total_ certainty of correctness.
+Lawless type classes make this difficult to do: compare the number of
+abstractions built on `Functor` or `Traversable` as opposed to `Foldable`.
+
+Thus, type classes having laws provides both ease of understanding and
+additional flexibility.

+
+## Overview
+
+MLabs has been working on developing two Plutus Use cases, specifically:
+
+- [Use Case: Lendex](#use-case-lendex) based on the specification of 
+  [Plutus Use case 3](https://github.com/mlabs-haskell/plutus-use-cases/tree/documentation#use-case-3-lending-and-borrowing-collateral-escrow-flashloans).
+
+- [Use Case: NFT](#use-case-nft) based on the specification of 
+  [Plutus Use case 5](https://github.com/mlabs-haskell/plutus-use-cases/tree/documentation#use-case-5-nfts-minting-transfer-buying-and-selling-nfts).
+
+Please refer to each individual Plutus Use Case for more specific information.
+
+### Prerequisites
+
+- Git
+- Curl
+- Nix
+
+### Building, Testing, Use
+
+# HLS setup (tested for Visual Studio Code)
+Start editor from nix-shell. Let the editor find the correct version of haskell-language-server binary.
+#### On Unix Systems
+
+*It is recommended that all current updates to your system be done before
+installation*
+
+1) ***Install basic dependencies***
+
+```bash
+sudo apt install curl
+sudo apt install git
+```
+
+2) ***Clone Directory***
+
+Create a directory and clone the project:
+
+```bash
+git clone https://github.com/mlabs-haskell/plutus-use-cases.git
+```
+
+3) ***Install Nix***
+  
+  1) **Setup Nix**
+
+  ```bash
+  $ curl -L https://nixos.org/nix/install | sh
+  ```
+    - *There is a issue with nix correctly adjusting the PATH in some machines. 
+      Please re-start your terminal and make sure Nix is in the path (`nix --version`).
+      See this discussion if you are having this issue: [https://github.com/NixOS/nix/issues/3317](https://github.com/NixOS/nix/issues/3317).*
+
+    - *The direct link to the nix download page for reference: [https://nixos.org/download.html](https://nixos.org/download.html).*
+
+   2) **Set up binary cache** 
+   
+   **note: Make sure to set up the IOHK binary cache. If you do not do this, you
+            will end up building GHC, which takes several hours. If you find
+            yourself building GHC, STOP and fix the cache.**
+	
+    - To set up the binary cache:
+		
+    * On **non-NixOS** machines: 
+  
+  Create a nix directory and file in the `etc` directory.
+			
+       1) `sudo mkdir /etc/nix`
+			
+       2) `sudo touch /etc/nix/nix.conf`
+			
+     *Then edit your `nix.conf` file to add:*
+		
+         `substituters        = https://hydra.iohk.io https://iohk.cachix.org https://cache.nixos.org/`
+         `trusted-public-keys = hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ= iohk.cachix.org-1:DpRUyj7h7V830dp/i6Nti+NEO2/nhblbov/8MW7Rqoo= cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=`
+     
+     
+  * On **NixOS** Machines, add the following NixOs options:
+         
+         `nix = {
+          binaryCaches          = [ "https://hydra.iohk.io" "https://iohk.cachix.org" ];`
+         `binaryCachePublicKeys = [ "hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ=" "iohk.cachix.org-1:DpRUyj7h7V830dp/i6Nti+NEO2/nhblbov/8MW7Rqoo=" ];
+          };`
+
+Please see the original documentation at IOHK for reference: 
+- [How to set up the IOHK binary caches](https://github.com/input-output-hk/plutus/blob/master/README.adoc#iohk-binary-cache)
+
+4) ***Create nix shell***
+
+Go to the `plutus-use-cases/mlabs` directory run the `nix-shell` command:
+```bash
+	$ nix-shell
+```
+- *note: This will take some time on the first run, as the dependencies get built locally.*
+
+### Documentation
+Currently the documentation is done via this document which can 
+be found in the [MLabs gitHub repository](https://github.com/mlabs-haskell/plutus-use-cases/tree/main/mlabs)
+
+### Testing
+For an overview of the test coverage and implementation refer to the individual
+cases documentation and the [test folder](https://github.com/mlabs-haskell/plutus-use-cases/tree/main/mlabs/test).
+
+#### Running Tests
+*TODO: Add the explanation of how to run tests*

+--------------------------------------------------------------------------------
+
+## Use Case: Lendex
+
+### Lendex: Description
+
+The Lendex Use Case is based on the Open Source, Non-Custodial Aave Protocol,
+described in the [Aave Protocol
+Whitepaper](https://github.com/aave/aave-protocol/blob/master/docs/Aave_Protocol_Whitepaper_v1_0.pdf).
+The use case can be summarised as a platform for a decentralised, pool-based,
+loan strategy.
+
+As described in the whitepaper, the model relies on Lenders depositing (Cardano)
+cryptocurrency in a Pool Contract. The same Pool Contract provides a source for
+funds to be borrowed by Borrowers through the placement of a collateral. Loans do
+not need to be individually matched, but rather rely on the pooled funds, the
+amounts borrowed and their respective collateral. The model enables instant
+loans and the interest rate for both borrowers and lenders is decided
+algorithmically. A general description of the interest algorithm is:
+
+- Borrower's interest is tied to the amount of funds available in the pool at
+  a specific time - with scarcity of funds driving the interest rate up.
+- Lender's interest rate corresponds to the earn rate, with the algorithm
+  safeguarding a liquidity reserve to guarantee ease of withdrawals at any
+  given time.
+

+--------------------------------------------------------------------------------
+
+## Use Case: NFT
+
+### NFT: Description
+
+The core functionality of the Non Fungible Tokens(i.e. NFTs) Use Case revolves
+around minting, sending, receiving NFTs into a Cardano wallet.
+
+NFTs are a digital asset that represents real-world objects. They can be bought
+and sold online, and act as a proof of ownership for the underlying asset they
+are meant to represent. Fungibility is the property of an asset to be
+interchangeable with its equal value in another fungible asset (example: $1 and
+10x $0.10 are interchangeable). Given that real-world objects cannot be replaced
+as easily with equivalent objects is a propert reflected in the nature of NFTs.
+
+For more details on NFT's refer to:
+
+- [Forbes: What You Need To Know About NFT's](https://www.forbes.com/advisor/investing/nft-non-fungible-token/)
+- [Cambridge Dictionary: nonfungible](https://dictionary.cambridge.org/us/dictionary/english/nonfungible)

+# Lendex Endpoints Specification
+
+This document describes the endpoint-level bahaviours we want to guarantee for the Lendex Contract
+
+This will include every current/planned endpoint, and for each Endpoint, a list of:
+- input type
+- prerequiste actions/endpoint calls (implicit state required for the call to succeed on both wallet and script state, implied previous endpoint calls from the user)
+- user role qualifications, if any
+- expected effects
+- known invariant effects/invalid inputs
+- known risks which must be mitigated
+
+
+
+## About the Lendex Contract
+
+The Lendex Contract is a cardano adaptation of the Aave lending protocol.
+
+In Aave, tokens are used to provide the infrastructure of a savings & loan bank on the blockchain.
+
+Aave supports multiple currencies, and is mainly used to create Collateralized Debt Positions across currencies,   Aave will have individual Lendex contract instances available for each currency.
+
+A user can deposit the currency tied to a given Lendex Contract Instance, and mint a token called an `aToken` (so for `Ada`, `aAda`, `USD`, `aUSD` etc)
+
+These `aToken`s can then be supplied as Collateral against a loan (usually in a different currency)
+
+when interest is paid against the loan, this increases the supply of the underlying token, while no additional aTokens are minted, the result is that aToken value has increased, as the aToken exchange rate corresponds to the ratio of (all aTokens in circulation) : (all underlying tokens in the lendex contract).
+
+On user roles (Actor types):
+Almost all users will be suppliers within the system, being a supplier is _required_ to be a borrower, though many users who act as a supplier will never be borrowers.
+
+Additionally since LQ will be distributed among suppliers, Many (though not necessarily all) Governor users will also be suppliers.
+
+Liquidators need not be Suppliers though.
+
+Attackers will assume other roles, attempt to cause invariant behaviours, or take advantage of system rules such that they profit at the expense of the contract or it's users, we want to prevent these kinds of attacks or make them less profitable
+
+
+## Admin Contract
+
+### StartParams
+
+input: Mlabs.Lending.Contract.Api.StartParams
+
+prerequisite: none
+
+behaviour: instantiate a User Contract with the input as its initial parameters.
+
+### AddReserve
+
+input: Mlabs.Lending.Contract.Api.AddReserve
+
+Prerequisite: none
+
+behaviour: 
+
+-- @anton:  what does this endpoint do?
+
+## Oracle Contract
+
+### SetAssetPrice
+
+input: Mlabs.Lending.Contract.Api.SetAssetPrice
+
+prerequisite: none
+
+behaviour: defines the conversion rate from Ada to a given Underlying token based on input values
+(input specifies a `Coin` and a `Ray` (rational))
+
+in the future we should adjust the oracle to accept information from a trusted source.
+
+## User Contract
+
+All Lendex endpoints rely on the Lendex being initialized through a call to `StartParams`
+
+### Deposit
+
+input:
+Mlabs.Lending.Contract.Api.Deposit (amount, asset)
+
+Prerequisite: wallet holds underlying currency for Market
+
+Expected outcome: 
+Wallet balance of underlying token reduces by (x * e) (plus fees).
+Wallet balance of aToken increases by x.
+where
+  x = amount of atokens specified in request body, rounded down such that the wallet has enough underlying token (if necessary)
+  e = exchange rate aToken: underlying
+
+if this transaction deposits Ada into the contract, the stake delegation of the user should be maintained.
+
+Invariant outcomes:
+the user should not be able to call a negative number in the request body at all, and should not be able to burn tokens using the endpoint under any circumstances.
+
+### Withdraw
+
+input:
+Mlabs.Lending.Contract.Api.Withdraw (amount, asset)
+
+Prerequisite: The user must hold aTokens for the market in question, making the `Deposit` endpoint necessary
+
+
+Expected outcome:
+Wallet Balance of aToken is reduced by x.
+
+Wallet balance of underlying is increased by (x * e) (less fees)
+atokens are burned AND any global state tracking total aTokens in circulation is adjusted.
+
+if another actor in the system has borrowed the underlying currency and paid interest, than the value of e should increase over time, this should be mechanical so it should be testable
+where
+  x = amount of atokens specified in request body, rounded down such that the wallet has enough aTokens (if necessary)
+  e = exchange rate aToken: underlying
+  
+if user A calls Mint... and then a user B borrows the underlying for the market and holds the borrow for a sufficient length of time to incur interest before repaying, then repays the loan, then the exchange rate should change, meaning user A will have more funds after calling Redeem than when they called Mint...
+
+invariant outcomes:
+negative numbers used for request body should NEVER result in a mint operation, furthermore, minting of aTokens must never happen on this endpoint.
+
+`e` must always be greater than or equal to the value of `e` at the time of the mint operation. aToken value never goes down.
+
+other notes:
+
+
+### SetUserReserveAsCollateral
+
+input:
+Mlabs.Lending.Contract.Api.SetUserReserveAsCollateral
+(asset, useAsCollateral, portion)
+(asset *must* refer to an aToken)
+
+prerequisite: user must have a reserve of deposited aTokens in wallet, implying that the user has previously called `Deposit`
+
+collateral ratios are calculated using each aToken : underlying exchange rate, then the exchange rate between that underlying token and Ada, which is provided by the Oracle - this way the collateral and the borrowed currency can be compared via relative value in Ada.
+
+behavior:
+let `userTokens` equal amount of `asset` in user wallet / provided utxos
+let `contractTokens` equal amount of `asset` currently locked as collateral for this user
+if useAsCollateral is True, then move (`userTokens` of `asset` * `portion`) from User wallet to contract and lock as collateral
+if useAsCollateral is false, then move (`contractTokens` of `asset` * `portion`) from contract to user wallet rounding down to ensure that the user does not go below minimum collateral ratios for this Lendex/User contract
+
+@anton - why is the `useAsCollateral` flag necessary? the Api for this endpoint feels a bit strange
+
+`asset` must refer to a supported token for this Lendex
+
+### Borrow
+
+Input:
+Mlabs.Lending.Contract.Api.Borrow
+(amount, asset, rate)
+ 
+
+Users: Borrowers
+
+Prerequisite:
+the user must have an appropriate amount of aTokens already held in the contract Collateral such that their borrow specifications can be met without putting them below minimum collateral Ratio
+
+collateral ratios are calculated using each aToken : underlying exchange rate, then the exchange rate between that underlying token and Ada, which is provided by the Oracle - this way the collateral and the borrowed currency can be compared via relative value in Ada.
+
+expected outcomes:
+- interest must be advanced on any outstanding borrows for this user - all calculations must use this amount and not the pre-interest amount.
+
+- wallet of user balance increases in `amount` of the Lendex's underlying token.
+- sufficient state must be maintained such that the user's outstanding borrow can always be known or accurately calculated, including interest.
+- if the user has existing borrows against their collateral, this must be considered as well such that the user's maximum borrow amount is never exceeded, interest should be recalculated before this check as well if needed.
+
+invariant behaviours:
+the user should not be able to specify negative amounts to borrow or provide collateral.  there should be no input such that this endpoint releases collateral to the user.
+
+Attack Vectors:
+
+Market Manipulation
+a user may attempt to manipulate the market or tamper with oracle behavior, being able to take out a loan during a price fluctuation (where the value of the underlying Token being borrowed is moved down, or the value of the collateral is move upward) allowing a borrow of more funds than the collateral provided once prices normalize
+
+This may require mitigation with time-weighted-averaging to the contract's benefit. 
+
+### Repay
+
+input:
+Mlabs.Lending.Contract.Api.Repay
+(amount, asset, rate)
+
+Users: Borrowers
+
+Prerequisite: 
+the user must have a loan, and in general will have Collateral to secure the loan up to the collateralRatio for the Lendex
+
+there are edge cases where we are unable to liquidate or have not yet liquidated the user, and they repay a portion of the loan, saving the loan from liquidation.
+
+expected outcomes
+interest against the loan should be recalculated.
+the wallet of the user will decrease by the specified amount from input in the Market's underlying Currency (or round down if the amount available is less than the amount in the input)
+the outstanding loan payment will be reduced by the amount paid, less interest applied against the loan
+Collateral is not released on this endpoint, even if the borrow amount is totally paid off.
+
+if repaying Ada, the user's stake delegation should be changed to some default? - if this feature is available in plutus
+
+invariant outcomes:
+can't repay a negative amount but 0 is ok.
+
+### SwapBorrowRateModel

+### LiquidationCall

+# NFT Contract Specification
+
+This project adapts the Ethereum-style approach to NFTs as a digital certificate of authenticity or ownership, it allows a creator to make a digital asset representing some artwork, then sell the asset, and for owners of the asset to be confirmed.
+
+ownership can only be transferred through the contract, so when the asset is re-sold, a royalty to the artist can be enforced
+
+## Author Contact
+
+### StartParams
+
+prerequisite: none
+
+input:
+Mlabs.Nft.Contract.Api.StartParams
+(content, share, price)
+
+behavior:
+instantiates the 'User' Contract, which represents an asset described by `content`
+the author is set to the original owner 
+the entire `StartParams` will need to be kept as some internal state to be referenced/updated, along with the author and the current owner
+
+## User Contract
+
+all endpoints on this contract presume that AuthorContract.StartParams has been called. 
+
+### SetPrice
+
+prerequiste: none beyond contract instantiation
+must be the current owner
+
+input:
+Mlabs.Nft.Contract.Api.SetPrice
+
+behavior:  
+updates the `price` parameter needed for the `Buy` endpoint
+
+### Buy
+
+prerequisite: user must have the necessary ada in their wallet
+the current asking price specified by a call to either `StartParams` or `SetPrice` must be a Just.   if it is a Nothing, then the asset is not for sale.
+
+input:
+Mlabs.Nft.Contract.Api.Buy
+(price, newprice)
+
+behavior:
+
+if the Buy.price is greater than or equal to the asking price, the user's wallet will be reduced by Buy.Price Ada (the contract must fail if the user has less than the specified Buy.price)
+the funds sent by the caller are split such that the `share` parameter amount is sent to the author, and the remainder is sent to the current owner
+the owner is set to the caller if the above is successful
+the asking price is set to the Buy.newprice

+# Nix tools for Mlabs Plutus Use Cases
+
+This directory contains all of the nix helper functions used to build our
+dependencies.
+
+# Formatting
+
+Use nixfmt (provided by the shell) to format the nix sources.
+
+# Niv dependency pinning
+
+Use `niv` to update / modify nix dependencies.
+
+# Updating plutus
+
+In order to update the plutus revision, a few steps must be taken:
+
+- `niv update plutus -r <revision>` will update Nix's plutus revision which will
+  also produce a new shell
+
+- You should update non-plutus entries in the sha256map in `./nix/haskell.nix`.
+  You can copy from the plutus repo
+  [here](https://github.com/input-output-hk/plutus/blob/master/nix/pkgs/haskell/haskell.nix)
+
+- Update the revision in `cabal.project` and paste the plutus repo's
+  `cabal.project` contents after the `*replace here*` separator
+
+Now everything should be updated, good luck fixing compile errors!

+# Governance Example Spec
+
+This will provide some simple governance functions as example behavior to be used across projects and as a simple demonstration of best-practices
+
+After the initial scaffold, we may adjust the governance contract to perform initiation and update features for contract configuration.
+
+We may also move some of the implementations into an open-source library, where possible
+
+This Contract will deal with a custom, pre minted token called GOV.  
+
+in reality this GOV token can be any token at all, the primary purpose of the contract is to allow users to store and retreive GOV tokens, report on GOV token holdings (as they may be used in a vote), and provide rewards.
+
+For this contract, the primitive Plutus API, and not the state machine API will be used.
+
+## Governance Contract:
+
+### Deposit
+prerequisites: 
+user has specified amount of GOV tokens
+
+input: { amount :: Integer }
+
+behaviors:
+
+user must provide `amount` of GOV tokens to contract or else the contract errors out.
+`amount` of GOV tokens associated with this user deposit must be reportable and we must be able to query this information knowing only the user's address PubKey
+
+we should mint xGOV tokens (this may be a configurable behavior in a library function to match the input GOV tokens,  xGOV tokens must be returned in order to claim GOV tokens from `Withdraw`)
+
+user cannot provide negative inputs
+
+### Withdraw
+
+prerequisites: 
+user has successfully called deposit, 
+user has specified amount of xGOV tokens in their wallet
+
+input: { amount :: Integer }
+
+behavior:
+transfer `amount` of user-provided xGOV tokens to contract and burn them
+transfer `amount` of GOV tokens to the user
+
+if user does not have provided amount of xGOV,  error.
+
+(because of how xGOV tokens and voting work, you must withdraw and redeposit your GOV tokens for your vote weight to change)
+
+user cannot provide negative inputs
+
+### ProvideRewards
+Prerequisites:
+user must have all the tokens and amounts in the specified Value
+
+input: PlutusTx.Value
+
+behaviors:
+move all rewards from user wallet, divided as evenly as possible to all stakers of GOV tokens, send these tokens directly to the stakers
+error out if there are no GOV tokens staked
+return any remainder tokens to the caller (only for smallest possible units)
+
+(we may create an alternative version where stakers can claim their rewards within the contract, as this is more conducive to futures markets (similar to xGOV tokens).
+
+### QueryBalance
+
+input: { address :: PubKey }
+
+returns { amount :: Integer }
+
+returns the total number of GOV tokens currently stored under the specified address. (may include multiple deposits, partial or full withdrawals may have occured)
+
+this is used for determining vote weight in democratic procedures
+
+

+# NFT marketplace PAB
+
+This executable runs PAB with NFT marketplace contracts.
+
+To serve contract PAB requires:
+ - Cardano node  (socket path must be set through config, see `plutus-pab.yaml.sample`)
+ - cardano-wallet (url must be set through config, see `plutus-pab.yaml.sample`)
+ - chain-index (url must be set through config, see `plutus-pab.yaml.sample`)
+
+To be able to sign transactions `--passphrase` need to be provided at PAB launch (see `cabal exec nft-marketplace -- --help`). That passphrase should be for wallet from cardano-wallet (WBE) which `id` will be used for contract activation.
+
+PAB launch example:
+```
+cabal exec nft-marketplace -- --config path/to/plutus-pab.yaml --passphrase walletA_passphrase migrate (creates database)
+
+cabal exec nft-marketplace -- --config path/to/plutus-pab.yaml --passphrase walletA_passphrase webserver
+```
+
+To activate NFT admin contract:
+```
+curl --location --request POST 'localhost:9080/api/contract/activate' \
+--header 'Content-Type: application/json' \
+--data-raw '{
+    "caID": {
+        "tag": "NftAdminContract"
+    },
+    "caWallet": {
+        "getWalletId": "walletA_id"
+    }
+}'
+```
+
+To activate NFT user contract:
+```
+curl --location --request POST 'localhost:9080/api/contract/activate' \
+--header 'Content-Type: application/json' \
+--data-raw '{
+    "caID": {
+        "tag": "UserContract",
+        "contents": {
+            "app'\''symbol": {
+                "unCurrencySymbol": "6666"
+            }
+        }
+    },
+    "caWallet": {
+        "getWalletId": "walletA_id"
+    }
+}'
+```
+! Note - this data from the example above:
+```
+"contents": {
+  "app'\''symbol": {
+    "unCurrencySymbol": "6666"
+    }
+  }
+```
+provided only as example, real `NftAppSymbol` data should be obtained from the state of admin contract.

+   We can't get rid of hard-coding the CurrencySymbol of UniqueToken at the moment since the mintContract produces it

+   to a Contract monad or using a similar approach such as ScriptM, which is operationally heavy and isn't worth doing.

+
+input:

+(price, newprice)
+
+behavior:
+
+if the Buy.price is greater than or equal to the asking price, the user's wallet
+will be reduced by Buy.Price Ada (the contract must fail if the user has less
+than the specified Buy.price) the funds sent by the caller ('the buyer') are
+split such that (`share` * `price` parameter amount) is sent to the author, and
+the remainder is sent to the current owner.
+
+for example, if the author set a share to 1/10, and the buyer paid 100 ada,  the
+authoer would receive 10 ada and the owner would receive the rest. the owner is
+set to the caller if the above is successful the asking price is set to the
+Buy.newprice.
+
+### QueryCurrentOwner
+
+Returns the address of the current owner.
+
+### QueryCurrentPrice
+
+Returns the current `price` parameter so that a potential buyer can purchase the
+item.

Subject: [PATCH 323/451] Convert nix setup to flakes (#292)

* Convert Nix setup to flakes

Start converting nix setup to flakes

WIP: flake conversion

WIP: Use sources.nix for sha256map for now

WIP: Compatibility shell.nix

Better compatibility shell.nix

Stop using sources.nix for sha256map

Use plutusPkgs for libsodium-vrf

Remove redundant let bind

Put shell config in right place

Use plutus for fourmolu

Newer version of fourmolu requires build

Compatibility default.nix

Remove redundant modules

Remove outdated info from readme

Add explanatory comment to haskell.nix module

Add flake-compat to flake inputs

Add all executables to checks output

Go back to using niv for sha256map

Fix/update nix readme

Also use plutusPkgs for niv

Add flakes transition notes to nix readme

Update CI

Add .envrc and .direnv/ to gitignore

Fix hoogle

Add experimental features flag to build CI

Add yet another flag to build CI

Fix path in CI

Use stack from plutus pkgs

Re-add update.nix

Temporarily disable tests in checks

Add experimental-features to extra_nix_config

* Fix cross-platform support

* Fix build CI

* Update nix readme

* Fix gitignore

+
+# Using flakes commands
+
+This repository recently switched to flakes, a fairly new (and still experimental)
+feature of the nix package manager. Flakes bring a lot of improvements to nix,
+including evaluation caching and greater consistency and reproducibility.
+
+This section is intended to help you transition to using flakes, illustrating flake
+equivalents of old `nix-*` commands.
+
+**Note**: You will need Nix version 2.4 or greater to use the new `nix` command
+and subcommands
+
+**Note**: Due to the use of IFD ("import from derivation") in haskell.nix, `nix flake show`
+and `nix flake check` do not currently work.
+
+## `nix-shell`
+
+Use `nix develop`
+
+## `nix-build`
+
+Use `nix build`
+
+### Building project components
+
+Previously, to build specific project components, `nix-build -A mlabs-plutus-use-cases.components.*`
+could be used. Project components can now be identified using the flake selector `#` followed by
+cabal-like syntax.
+
+For example, to build the executable `lendex-demo`:
+
+Old:
+
+`nix-build -A mlabs-plutus-use-cases.components.exes.lendex-demo`
+
+New:
+
+`nix build .#mlabs-plutus-use-cases:exe:deploy-app`
+
+### Build all derivations that will be built in CI
+
+(See note about IFD problem above).
+
+As currently configured, `nix flake check` will build all project components, including the tests
+and executables. If the `-L` flag is included, the build logs will be fully printed to stdout.
 
-- `niv update plutus -r <revision>` will update Nix's plutus revision which will
-  also produce a new shell
+You can also run the `run-tests.sh` script in the repository root which will build all project
+components.
 
-- You should update non-plutus entries in the sha256map in `./nix/haskell.nix`.
-  You can copy from the plutus repo
-  [here](https://github.com/input-output-hk/plutus/blob/master/nix/pkgs/haskell/haskell.nix)
+## More helpful commands
 
-- Update the revision in `cabal.project` and paste the plutus repo's
-  `cabal.project` contents after the `*replace here*` separator
+See all of the flake outputs: `nix flake show`
+See flake metadata, including inputs: `nix flake metadata`
 
-Now everything should be updated, good luck fixing compile errors!
+## Compatibility
 
+In case you cannot upgrade to Nix 2.4 or prefer the older interface, compatibility `shell.nix` and
+`default.nix` remain in this repository.

Subject: [PATCH 325/451] NFT: Implement fees support in quickcheck model
 (#295)

* Fix Auction fees

Gov tokens were paid to user that called `auction-close`, not to the
one that won the auction

* Fix NFT list insertion

When inserting new NFT after a node with bid ADA, bid ADA wasn't
specified to be sent back, and  balancing caused bugs

* Add fees support to QuickCheck model

* Fix build

 # Pinning git dependencies
 
-Use `niv` to update the git dependencies in `haskell-nix-cabal.project`.
-
-- to update a pinned dependency:
-
-```shell
-niv update <dependency_name> -r <dependency_tag>
-```
-
-This will update both the revision, and the sha256 of the said dependency, that
-will then get pulled by haskell-nix.
-
-To update all of the dependencies with `niv`, run the `update-sha256map.sh` script
-in the repository root.
-
-# Updating plutus
-
-In the case of a `plutus` upgrade, you _must_ also update the `rev` field of `plutusSrc`
-in `flake.nix` in addition to the steps above:
-
-```shell
-niv update plutus -r <revision>
-```
-
-then
-
-```nix
-# ../flake.nix
-{
-  inputs = {
-
-    plutusSrc = {
-      type = "github";
-      owner = "input-output-hk";

-      flake = false;

-
-  }
-
-}
-```
+Git dependencies are pinned in the `inputs` of the flake. Make sure to set `flake = false;` when adding a new dependencies. When upgrading an existing dependency, replace the commit hash in its `url`.

-As currently configured, `nix flake check` will build all project components, including the tests

-You can also run the `run-tests.sh` script in the repository root which will build all project

+# IMPORTANT NOTES ABOUT THIS FILE
+#
+# a) cardano-node does not parse 'yaml' but only 'json'. We use yaml as a nicer/simpler format
+#    and convert it as json when generating the underlying configuration for the node.
+#
+# b) the `systemStart` is hard-coded here to please the parser but is replaced dynamically
+#    by the same code generating the final node configuration for integration.

-# IMPORTANT NOTES ABOUT THIS FILE
-#
-# a) cardano-node does not parse 'yaml' but only 'json'. We use yaml as a nicer/simpler format
-#    and convert it as json when generating the underlying configuration for the node.
-#
-# b) the `systemStart` is hard-coded here to please the parser but is replaced dynamically
-#    by the same code generating the final node configuration for integration.
-#

We need those instances to be written manually for now to integrate
with transaction library since there is no `makeIsData` there for now
