+36 key unibody split
+
+* Keyboard Maintainer: [Jason Hazel](https://github.com/jasonhazel)
+* Hardware Supported: Bad Wings v1
+* Hardware Availability: [Hazel's Garage](https://shop.hazel.cc/products/bad-wings)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make hazel/bad_wings:default
+
+Flashing example for this keyboard:
+
+    make hazel/bad_wings: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).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Bootmagic reset**: Hold down the top-left key and plug in the keyboard
+* **Physical reset button**: Hold Xiao B button, press Xiao R button, release B
+* **Keycode in layout**: There is no key mapped to `QK_BOOT` in the pre-created keymaps, but you may assign this key in any keymaps you create
