+# 🎮 VitaPad
+Use your PlayStation Vita as USB gamepad with rear touchpad controls.
+
+## Features
+This is an improved version of the [vitastick plugin by xerpi](https://github.com/xerpi/vitastick) with added functionality, improved code readability, and some major changes that increase reliability and usability.
+- Simple and elegant interface
+- Ability to use rear touchpad controls (L2/R2 & L3/R3)
+- Reduces clock frequencies when active to reduce power consumption
+- Disables use of power and PS buttons while gamepad functionality is active (this allows the gamepad to continue working as necessary)
+- Automatically disconnects after 2 minutes of inactivity
+
+## 🚀 Installation
+1. Download the plugin and VPK from the [releases page](https://github.com/carlelieser/vitapad/releases).
+2. Copy `vitapad.skprx` to `ur0:/tai/`.
+3. Add `vitapad.skprx` to your `config.txt` under the kernel section. 
+    ```
+    *KERNEL
+    ur0:tai/vitapad.skprx
+    ```
+4. Install `vitapad.vpk`.
+
+## 🐈 Usage
+Open the VPK and connect your Vita via USB. Press X to initialize the gamepad functionality. Hold SELECT + START to disconnect. Enjoy!
