 #### Template and naming
 
-There is a template module to easily start a new feature. When creating a new module, you can just copy paste the template. It is
-located [here](../features/template).
-
-For the naming rules, please follow what is being currently used in the template module.
+This documentation provides you with the steps to install and use the AS plugin for generating modules in your project. 
+The plugin and templates will help you quickly create new features with a standardized structure.
+
+##### A. Installation
+
+Follow these steps to install and configure the plugin and templates:
+
+1. Install the AS plugin for generating modules :
+   [Generate Module from Template](https://plugins.jetbrains.com/plugin/13586-generate-module-from-template)
+2. Import file templates in AS :
+   - Navigate to File/Manage IDE Settings/Import Settings
+   - Pick the `tools/templates/file_templates.zip` files
+   - Click on OK
+3. Configure generate-module-from-template plugin : 
+   - Navigate to AS/Settings/Tools/Module Template Settings
+   - Click on + / Import From File
+   - Pick the `tools/templates/FeatureModule.json`
+
+Everything should be ready to use.
+
+##### B. Usage
+
+Example for a new feature called RoomDetails:
+
+1. Right-click on the features package and click on Create Module from Template
+2. Fill the 2 text fields like so:
+    - MODULE_NAME = roomdetails
+    - FEATURE_NAME = RoomDetails
+3. Click on Next
+4. Verify that the structure looks ok and click on Finish
+5. The modules api/impl should be created under `features/roomdetails` directory.
+6. Sync project with Gradle so the modules are recognized (no need to add them to settings.gradle).
+7. You can now add more Presentation classes (Events, State, StateProvider, View, Presenter) in the impl module with the `Template Presentation Classes`.
+   To use it, just right click on the package where you want to generate classes, and click on `Template Presentation Classes`. 
+   Fill the text field with the base name of the classes, ie `RootRoomDetails` in the `root` package.
+   
 
 Note that naming of files and classes is important, since those names are used to set up code coverage rules. For instance, presenters MUST have a
 suffix `Presenter`,states MUST have a suffix `State`, etc. Also we want to have a common naming along all the modules.
