-## Description
+## 📖 Description
 
 ControllerBuddy is an advanced gamepad mapping software that supports the creation of input profiles for complex target applications such as flight simulators.
 
 In addition to the simple mapping of buttons and axes of a physical game controller to keyboard and mouse input, ControllerBuddy also supports feeding input commands to a virtual joystick device (vJoy / uinput).
 
 The goal of ControllerBuddy is to allow the user to control target applications exclusively with a gamepad without ever having to reach for a keyboard or mouse.
