## What it is
A Rust command-line utility for programming small CH57X-based macro keyboards (vendor/product IDs 1189:8890, 1189:8840, 1189:8842) commonly sold on AliExpress. It lets users configure key mappings, layers, and LED settings via config files, replacing the Windows-only vendor software.

## Use cases
- program a cheap aliexpress macro keyboard on linux
- remap keys on a ch57x mini keypad
- configure keyboard layers and knobs from a config file
- replace the ugly windows-only vendor software for my macro pad
- change led settings on a 3x4 macro keyboard
- validate and upload keyboard config over usb

## When to choose
- you own a supported ch57x keyboard (1189:8890, 1189:8840, or 1189:8842) and want cross-platform configuration
- you prefer declarative config files over vendor GUI tools
- you want to program all keys at once and access hidden keyboard features

## When to avoid
- your macro keyboard uses a different chipset or vendor/product ID
- you need a graphical configuration interface
- you need to program the keyboard over Bluetooth rather than USB
