On Windows, create a "krtkus" folder in qmk_firmware/keyboards and copy the contents of the qmk folder inside of it. Then in MSYS compile the firmware using the commands below.
Setup:
qmk setup
Compile:
qmk compile -kb krtkus -km default
Once the firmware is flashed, it provides key combinations to enter bootloader or clear the keyboard's persistent storage.
LShift + RShift + B- Puts the keyboard into bootloader mode for flashingLShift + RShift + C- Reinitializes the keyboard and reverts to the default keymap
