KMK is a feature-rich and beginner-friendly firmware for computer keyboards
written and configured in
[CircuitPython](https://github.com/adafruit/circuitpython). **KMK is currently
in public beta, however should handle most workflows without major issues**.
<!--
@klardotsh 06 July 2021: commented for now because CDN builds have been broken
for ages and folks are (reasonably) getting confused.
You can always find the latest releases on our CDN, in [compiled and
optimized](https://cdn.kmkfw.io/kmk-latest.zip) and [raw, hackable text
file](https://cdn.kmkfw.io/kmk-latest.unoptimized.zip) forms. These follow the
`master` branch here on GitHub.

## Features
2019-07-25 06:16:26 +02:00
- Fully configured through a single, easy to understand Python file that lives
on a "flash-drive"-esque space on your microcontroller - edit on the go
without DFU or other devtooling available!
- Single-piece or [two-piece split
keyboards](https://github.com/KMKfw/kmk_firmware/blob/master/docs/split_keyboards.md)
are supported
- [Chainable
keys](https://github.com/KMKfw/kmk_firmware/blob/master/docs/keys.md) such as
`KC.LWIN(KC.L)` to lock the screen on a Windows PC
- [Built-in unicode macros, including
emojis](https://github.com/KMKfw/kmk_firmware/blob/master/docs/sequences.md)
- [RGB underglow](https://github.com/KMKfw/kmk_firmware/blob/master/docs/rgb.md)
and [LED
backlights](https://github.com/KMKfw/kmk_firmware/blob/master/docs/led.md)
- One key can turn into many more based on [how many times you tap
it](https://github.com/KMKfw/kmk_firmware/blob/master/docs/tapdance.md)
- Bluetooth HID and split keyboards. No more wires.
## Getting Started
Our getting started guide can be found
[here](https://github.com/KMKfw/kmk_firmware/blob/master/docs/Getting_Started.md)
## The KMK Team
KMK is primarily written and maintained by @klardotsh and @kdb424, but
contributions are welcome from all, whether it's in the form of code,
documentation, hardware designs, feature ideas, or anything else that comes to
mind. A list of KMK's contributors can be found [on
GitHub](https://github.com/KMKfw/kmk_firmware/graphs/contributors).
> While Adafruit employees and affiliates are occasionally found in the commit
> log and their help has been crucial to KMK's success, KMK is not an official
> Adafruit project, and the Core team is not compensated by Adafruit for its
> development.
## Code Style
KMK uses [Black](https://github.com/psf/black) with a Python 3.6 target and,
[(controversially?)](https://github.com/psf/black/issues/594) single quotes.
Further code styling is enforced with isort and flake8 with several plugins.
`make fix-isort fix-formatting` before a commit is a good idea, and CI will fail
if inbound code does not adhere to these formatting rules. Some exceptions are
found in `setup.cfg` loosening the rules in isolated cases, notably
`user_keymaps` (which is *also* not subject to Black formatting for reasons
documented in `pyproject.toml`).
