 ## Install
 For stability, users are encouraged to import from a tagged release, not from the master branch, and to watch for new releases. This project does not yet have rigorous testing set up for it and new commits on the master branch are prone to break compatibility and are almost sure to change the import hash for the expression, thus the releases are currently `v0.x`.
-To import everything, use:

+You should generally import `domain.dhall`, which includes `Resource`, `ResourceType`, `Step`, `Task`, `Job`, `Group`, `Pipeline`, and `VarSource`, and merge it with the resource types that you need. For example,

 ## Intended Usage

 This repository allows the user to construct the type of `Resource` and of `ResourceType` based on a union that the downstream user constructs, consisting only of the resource types which the downstream user actually uses in their pipeline. This solves both the code-reusage problem, and keeps the implementation performant. For example:
