+# Description
+A keymap designed to be functional for development purposes - no flashing lights or gimmicks. PRTSC and DEL key in the top right corner.
+Solid backlight that changes red if CAPS is on and reverts back afterwards. Brightness retained in both cases.
+Backlight is disabled on suspend and restored upon wake-up.
+The 'Windows' key is a second FN key. This makes it more natural to use the encoder wheel (good luck trying to do it with one hand).
+
+Compile using `qmk compile -kb gmmk/pro/ansi -km andrewcharnley`
+
+# Encoder
+FN + Encoder scroll = media next/prev
+FN + Encoder press = media pause
+default encoder behavior = volume up/down
+
+# Function Layer
+FN + Up = increase brightness
+FN + Down = decrease brightness
+FN + Backslash = bootloader
+
