+# Frosty Flake Controller
+
+This is the firmware for Rev. 20140521 of the Frosty Flake controller
+by [Bathroom Epiphanies](http://bathroomepiphanies.com/controllers/),
+a replacement controller for the [Cooler Master Quick Fire
+Rapid](http://www.coolermaster.com/peripheral/keyboards/quickfirerapid/).
+
+The code was adapted from the [BathroomEpiphanies TMK
+Firmware](https://github.com/BathroomEpiphanies/epiphanies_tmk_keyboard/tree/master/be_controllers),
+but has been cleaned up to match the
+[schematic](https://deskthority.net/wiki/File:Frosty_Flake_Schematics.pdf)
+and gone through some minor refactoring for QMK.
+
+## 104 and 87 layout support
+
+Support for both 104 key and 87 key layouts is provided. See the
+keymaps `default` (104) and `tkl` (87) for example layouts.
+
+Keyboard Maintainer: QMK Community  
+Hardware Supported: Frosty Flake  
+Hardware Availability: https://1upkeyboards.com/qfr-frosty-flake-controller.html
