- *
- * If forced on, NKRO can be disabled via magic key (default = LShift+RShift+N)
- * until the next keyboard reset.
- *
- * NKRO may prevent your keystrokes from being detected in the BIOS, but it is
- * fully operational during normal computer usage.
- *
- * For a less heavy-handed approach, enable NKRO via magic key (LShift+RShift+N)
- * or via bootmagic (hold SPACE+N while plugging in the keyboard). Once set by
- * bootmagic, NKRO mode will always be enabled until it is toggled again during a

-
-![CU75](https://geekhack.org/index.php?action=dlattach;topic=91767.0;attach=179167;image)
-
-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 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.
