From the project

Firmware: The pinout is the same as the original reviung41, so the existing Reviung41 firmware (QMK or ZMK) works for this device.

[[ Build Guide ]](build.md) (work-in-progress)

[[ Stabilizer Installation ]](build.md#stabilizer-installation) I have not yet provided guidance on how to mod the bar from its stock-state to work with choc-v2 switches. The offset/bent portion of the bar needs to be nearly flat.
