- Replace ARDUINO_ROOT/hardware/arduino/variants/leonardo/pins_arduino.h with libraries/pins_arduino.h (back up the existing one)
- Replace ARDUINO_ROOT/hardware/arduino/boards.txt with the one from this repo.
- To program via USB, you need the actual Leonardo or LilyPadUSB bootloader. To install that, you'll need to use some kind of AVRISP. This is a good place to start: http://letsmakerobots.com/content/make-arduino-isp-programmer
