+
+A luxurious 75% keyboard with various layouts. Includes RGB underglow, backlight and an aluminium, brass and nylon case.
+
+Keyboard Maintainer: [Yiancar](https://github.com/yiancar) and [LFKeyboards](https://github.com/lfkeyboards)  
+Hardware Supported: PCB v1.0 (uses a 32u4)  
+Hardware Availability: [caps-unlocked.com](http://caps-unlocked.com/)
+
+This PCB uses lighting libraries from LFKeyboards
+
+Make example for this keyboard (after setting up your build environment):
+
+    make capsunlocked/cu75:default
+
+See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
