-Kitten Paw controller firmware
-======================
-Custom controller for the Costar Majestouch keyboard designed by bpiphany.
-
-*Note that this is not the official firmware*
-
-Build
------
-Move to this directory then just run `make` like:
-
-    $ make -f Makefile.lufa
-
-At the moment only the LUFA stack is supported.
-
-
-Bootloader
----------
-To enter bootloader by hardware use a magnet above the controller before connecting the usb cable.
-
-It is still possible to use Boot Magic and Command (LSFT+RSFT+PAUS) to access the bootloader though.
