 There is simple tutorial in [Tutorial](https://github.com/mcgurk/Arduino-USB-HID-RetroJoystickAdapter/tree/master/Tutorial) folder. I tried to make it as clear as possible, so even if you are not familiar with coding, you may can do modifications to it (example add a button).
 
 ## Polishing
-If you want that less than 16 buttons are shown in joystick-settings, edit Joystick.cpp/Joystick2.cpp/Joystick3.cpp "USAGE_MAXIMUM"-line (0x10 = 16). You may to have create new file after that, because all libraries are not recompiled every time and I don't know how to force full recompile.

 Adapter shows as "Arduino Leonardo", but if you want it to show some other name, edit `C:\Program Files (x86)\Arduino\hardware\arduino\avr\boards.txt`. You can even add sub menu to tools-menu by adding these lines (after editing boards.txt, you have to close and reopen Arduino IDE):
