I own some nice keyboards. QMK layout configs are stored in this repo.
- Download QMK Toolbox either from this repo, or from official source
- Enter a bootloader mode on a keyboard
- Unplug it
- Hold "bootloader combo" (usually space + b)
- Plug it back
- After few seconds let combo go
- In QMK Toolbox choose compiled keymap, correct microcontroller (usually shown when you connect a keyboard in bootloader mode)
- Click "flash"
- Done
