+# Default Unicorne Layout
+
+This is the default layout for Unicorne. The "lower" layer consists of symbols
+and navigation, while "raises' has numbers, some other symbols and function
+keys.
+
+Press `lower` and `raise` together activates `adjust` layer, with RGB controls,
+as well as access to reset/bootloader.

+
+A compact 40% (3x6\_4) single-piece angled ortholinear ergo keyboard kit inspired by crkbd, Kyria, Ferris and Reviung41. Features OLED display, audio buzzer, RGB LED underglow as well as encoders.
+
+* Keyboard Maintainer: [Yang Hu](https://github.com/yanghu)
+* Hardware Supported: Unicorne PCB 1.0
+* Hardware Availability: Open source design at https://github.com/yanghu/unicorne
+
+To enter bootloader, long press the reset button for 3-5 seconds then release. More details can be found at [keyboard wiki](https://github.com/yanghu/unicorne/wiki/Build-guide#testing-the-board). 
+
+Make example for this keyboard (after setting up your build environment):
+
+    make yanghu/unicorne: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).
