+## Features
+
+### Controller identification
+
+Controlify has the ability to identify the make and model of your controller automatically,
+and displays relevant button textures for your controller. This is also customizable, and 
+resource packs can add their own controller textures.
+
+### Joystick support
+
+You can connect any joystick and create your own mappings for it, allowing you to display custom
+textures for your joystick. These mappings are powered through resourcepacks, allowing creators
+to create mappings for everyone.
+
+### Container cursor
+
+Just like in bedrock edition, you can move a cursor across your inventory, and interact
+with it in a controller-friendly way.
+
+### Button guide
+
+The button guide is a simple overlay in-game that displays the buttons you can press
+based on your player's state and look direction. This is useful for new players, who
+have not yet memorised the controls.

 This mod is built around the fact that each controller is completely separate, with it's own configuration, bindings etc.

 GUI operation has been abstracted into a simple API, which allows other mods to easily add support for their own GUIs,
 without convoluted support throughout the whole mod's codebase, making it difficult for third parties to integrate.
 
+### Automatic controller deadzone calibration
+
+The deadzone values of your controller are automatically calibrated, 
+meaning you don't have to worry about it.

 ## What is to come?
