FAQ:

Q: I installed latest version of Arduino IDE but I can't find Leonardo under boards

A: Un-comment the Leonardo section in the "\hardware\arduino\boards.txt" file in your Arduino IDE install location

Q: I disabled all interrupts and entered infinite loop code on my board and now the bootloader won't start. How do I start it?

A: You need a programmer to program the bootloader again. Avoid disabling interrupts at all costs.
