+# For Science
+
+![for_science](https://raw.githubusercontent.com/peej/for-science-keyboard/master/pcb.png)
+
+A split ergo 4x5 keyboard with 3 thumb keys where each half is smaller than the 100x100mm cheap PCB production size. 
+Designed to be easy to build, it only supports serial communication over a TRRS cable and no LED support.
+The PCB is reversible, meaning that you use the same PCB for both the left and right halves and thus need two PCBs to create a full keyboard.
+
+* Keyboard Maintainer: [Peej](https://github.com/peej)
+* Hardware Supported: Pro Micro
+* Hardware Availability: [Github](https://github.com/peej/for-science-keyboard)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make for_science: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.
