+
+
+Custom handwired nicekey, a one key keyboard that writes random compliments.
+
+Keyboard Maintainer:  spydon  
+Hardware Supported: Custom handwired one key  
+Hardware Availability:
+
+Switch must be connected to pins C6 and B6. 
+
+Make example for this keyboard (after setting up your build environment):
+
+    make handwired/nicekey:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
