 Alternative Controller for HHKB Pro
 ===================================

-firmware source code is not open, of course. This means customizing this keyboard needs to replace original 
-controller with programmable one. This controller can work with HHKB Professional and Professional 2 model.

+Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. Just `make` with `KEYMAP` option like:
