How to support QMK

Quantum Mechanical Keyboard Firmware

This is a keyboard firmware based on the tmk_keyboard firmware with some useful features for Atmel AVR and ARM controllers, and more specifically, the OLKB product line, the ErgoDox EZ keyboard, and the Clueboard product line.

Supported Keyboards

The project also includes community support for lots of other keyboards.


QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, Hasu. The OLKB product firmwares are maintained by Jack Humbert, the Ergodox EZ by Erez Zukerman, and the Clueboard by Zach White.


Documentation is hosted on Gitbook and Github (they are synced). You can request changes by making a fork and pull request or by clicking the “suggest an edit” on any page.
