The default keymap is a testing keymap that is intended to make sure all of the keys on the matrix are working and properly assigned. [The original (minimal arduino sketch) firmware, with support for some unsupported controllers](https://git.40percent.club/di0ib/Misc/src/branch/master/polyandry) Keyboard Maintainer: QMK Community Hardware Supported: Polyandry PCB Hardware Availability: [Polyandry gerbers are on 40percent.club](https://www.40percent.club/2019/07/polyandry.html) Make example for this keyboard (after setting up your build environment): make 40percentclub/polyandry:default or qmk compile -kb 40percentclub/polyandry -km default Default firmware is for an Arduino Pro Micro knockoff. If you would like to specify a controller: make 40percentclub/polyandry/promicro:default or qmk compile -kb 40percentclub/polyandry/promicro -km default make 40percentclub/polyandry/teensy2:default or qmk compile -kb 40percentclub/polyandry/teensy2 -km default ## Bootloader Enter the bootloader in 3 ways: * **Bootmagic reset**: Hold down the top left key of the keyboard (top right or bottom left in horizontal configuration) * **Physical reset**: Briefly press the button on the bottom of the microcontroller or, if not present short the pin marked RST to a GND. * **Keycode in layout**: Press the key mapped to `RESET` if it is available See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
