+## Why Use ExUssd?
  ExUssd lets you create simple, flexible, and customizable USSD interface.
  Under the hood ExUssd uses Elixir Registry to create and route individual USSD session.

+## Documentation
+The docs can be found at [https://hexdocs.pm/ex_ussd](https://hexdocs.pm/ex_ussd).
+
 ## Installation
 
-To add ExUssd to your application application.
+If [available in Hex](https://hex.pm/docs/publish), the package can be installed
+by adding `ex_ussd` to your list of dependencies in `mix.exs`:
+
 
 ```elixir
 defp deps do
   [
-    {:ex_ussd, "~> 1.0.0"}
+    {:ex_ussd, "~> 1.0.0-rc-1"}
   ]
 end
 ```
 
-### Let's create a custom global values
+## Configuration
+
+Add to your `config.exs`
 
  ```elixir
 # config/config.exs
 # TODO: This are example values, replace them with your own
 config :ex_ussd,
   nav: [
-        ExUssd.Nav.new(type: :home, name: "HOME", match: "00", reverse: true, orientation: :vertical),
-        ExUssd.Nav.new(type: :back, name: "BACK", match: "0", right: 1),
-        ExUssd.Nav.new(type: :next, name: "MORE", match: "98")
+    ExUssd.Nav.new(type: :home, name: "HOME", match: "00", reverse: true, orientation: :vertical),
+    ExUssd.Nav.new(type: :back, name: "BACK", match: "0", right: 1),

       ],
- delimiter: ").",
- default_error: "invalid input,try again\n"
+  delimiter: ").",
+  default_error: "invalid input,try again\n"
 ```
 
 ## Usage
 
+### Settable Fields
+
+* **`:data`** Set data to pass through to next menu. N/B - ExUssd menu are stateful unless using ExUssd.new/2 with `:name` and `:resolve` as arguments;
+  ```elixir
+  data = %{name: "John Doe"}
+  # stateful
+  menu
+  |> ExUssd.set(data: data)
+  |> ExUssd.add(ExUssd.new("Check Balance", &check_balance/2))
+ 
+  # stateless
+  menu
+  |> ExUssd.add(ExUssd.new(data: data, name: "Check Balance", resolve: &check_balance/2))
+    ```
+
+* **`:delimiter`** Set's menu style delimiter. Default- `:`
+* **`:default_error`** Default error shown on invalid input
+* **`:error`** Set custom error message
+* **`:name`** Sets the name of the menu
+* **`:nav`** Its used to create a new ExUssd Nav menu
+* **`:orientation`** Sets the menu orientation. Available option;
+  - `:horizontal` - Left to right. Blog/articles style menu
+  - `vertical` - Top to bottom(default)
+* **`:resolve`** Navigates(invokes the next `ussd_init/2`) to the next menu
+* **`:should_close`** Indicate whether to USSD session should end or continue
+* **`:show_navigation`** Set show navigation menu. Default - `true`
+* **`:split`** Set menu batch size. Default - 7
+* **`:title`** Set menu title
+
+
 ### ExUssd Callbacks
 
 ExUssd provides you with 3 callbacks

   It's invoked once when the user navigates to that particular menu
