+24pad firmware
+==============
+
+24 key macro pad from half of a Lets Split.
+
+To use, drop this directory into the QMK source tree under keyboards/24pad.
+
+Make example for this keyboard (after setting up your build environment):
+
+ make 24pad:default
+
+Flashing example for this keyboard:
+
+ make 24pad:default:flash
+
+Bootloader
+----------
+Hold down top left key (in the corner closest to the microcontroller) and plug
+in the keyboard.
