+# Helix rev2
+
+A compact split ortholinear keyboard.
+
+* Keyboard Maintainer: [yushakobo](https://github.com/yushakobo)
+* Hardware Supported: Helix rev2 PCBs, Pro Micro
+* Hardware Availability: [PCB & Case Data](https://github.com/MakotoKurauchi/helix)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make helix/rev2:default:flash
+
+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).
