+# 2x5keypad
+
+![2x5keypad](http://jmcameron.net/2x5keypad-small.jpg)
+
+This Keypad has 2 rows x 5 columns of keys. It has the top/default layer that
+has a few handy navigation keys as well as one dedicated key to cycle through
+the layers. The second layer has some media keys. The third and fourth layers
+are currently undefined (although I may use them for inserting accented French
+characters). The keypad also includes three LEDs that show which layer is
+active (no lit LEDs means the default layer).
+
+Keyboard Maintainer: [Jonathan Cameron](https://github.com/jmcameron)  
+
+Hardware:
+  * Key switch holes cut in blank piece of copper-clad project board
+  * Uses Kailh Box White switches with relegendable keycaps
+  * Chassis is three layers of wood
+  * Handwired
+  * Uses a Pro Micro
+  * Includes a reset switch accessible by a hole on the bottom
+
+Make example for this keyboard (after setting up your build environment):
+
+    make handwired/2x5keyapd:default
+
+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. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
