 * 60% and 80% (TKL) pcbs are supported
 Changing Bootloader
 Build
 -----
 Move to this directory then just run `make`.
 For building you have to specify two build-options, LAYOUT and KEYMAP. The layout option defines
 pcb layout and can be either 60% or 80% at the momemnt. The keymap option selects your
 preferred keymapping.
 Move to this directory then just run `make LAYOUT=60 KEYMAP=ansi150`
 to compile a firmware for a 60% pcb with ANSI 150 key mapping.
