QMK (*Quantum Mechanical Keyboard*) is an open source community that maintains QMK Firmware, QMK Flasher, qmk.fm, and these docs. QMK Firmware is a keyboard firmware based on the [tmk\_keyboard](http://github.com/tmk/tmk_keyboard) with some useful features for Atmel AVR controllers, and more specifically, the [OLKB product line](http://olkb.com), the [ErgoDox EZ](http://www.ergodox-ez.com) keyboard, and the [Clueboard product line](http://clueboard.co/). It has also been ported to ARM chips using ChibiOS. You can use it to power your own hand-wired or custom keyboard PCB.

## Programming The Behavior Of Any Keycode ## Programming the Behavior of Any Keycode
When you want to override the behavior of an existing key, or define the behavior for a new key, you should use the `process_record_kb()` and `process_record_user()` functions. These are called by QMK during key processing before the actual key event is handled. If these functions return `true` QMK will process the keycodes as usual. That can be handy for extending the functionality of a key rather than replacing it. If these functions return `false` QMK will skip the normal key handling, and it will be up you to send any key up or down events that are required.

The music mode maps your columns to a chromatic scale, and your rows to octaves. This works best with ortholinear keyboards, but can be made to work with others. All keycodes less than `0xFF` get blocked, so you won't type while playing notes - if you have special keys/mods, those will still work. A work-around for this is to jump to a different layer with KC_NOs before (or after) enabling music mode. The music mode maps your columns to a chromatic scale, and your rows to octaves.

Now that you have a working board, it's time to get things in their permanent positions. I've often used liberal amounts of hot glue to secure and insulate things, so if that's your style, start spreading that stuff like butter. Otherwise, double-sided tape is always an elegant solution, and electrical tape is a distant second. Due to the nature of these builds, a lot of this part is up to you and how you planned (or didn't plan) things out.

This page describes the support for for AVR processors in QMK. AVR processors include the atmega32u4, atmega32u2, at90usb1286, and other processors from Atmel Corporation. AVR processors are 8-bit MCU's that are designed to be easy to work with. The most common AVR processors in keyboards have on-board USB and plenty of GPIO for supporting large keyboard matrices.
