+description: |
+  The Arduino Uno Rev3 is a board who's popularity lead to countless shields being developed for it. By
+  natural extension, once there were many shields designed for it, many other *boards* began to be developed
+  that were compatible to leverage the extensive available shields. Today, many dev kits come with Uno
+  headers to make it easy to work with them.
+
+  Note: ZMK doesn't support boards with AVR 8-bit processors, such as the ATmega32U4, because Zephyr™ only
+  supports 32-bit and 64-bit platforms. As a result, boards like the original Arduino Uno Rev3 itself are
+  *not* supported by ZMK.
