+===
+
+3x4/4x3 grid layout, multiple controllers supported
+- Pro Micro
+- PJRC Teensy 2.0
+
+(**The below are not currently ported:**)
+
+- PJRC Teensy LC/3.2 
+- PJRC Teensy 3.5/3.6
+- Adafruit ItsyBitsy ATMega32u4
+- Adafruit ItsyBitsy M0
+- Adafruit ItsyBitsy M4
+
+The matrix is electrically 1x12 with no diodes, with a thirteenth pin used for the column rather than a ground in order to be compatible with all the listed microcontrollers..
+
+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
+
