In this recipe, we will be using the @moduledoc and @doc reserved module attributes to add documentation to the modules we defined in the previous recipe, Enforcing behaviors.

Getting ready

How to do it…

To add documentation to our modules, follow these steps:

  1. We will start by adding module documentation to the randomizer.ex file. Add the following code below the use Behavior line:

    @moduledoc """
      This module specifies the interface for a randomizer behaviour by using the defcallback macro.

  2. Add the following module documentation to the my_module.ex file below the @behaviour Randomizer line:

    @moduledoc """
      This is a custom module to demo the implementation of behaviours.
