 If this bothers you, and you just want to send a true Z input by default when
 pressing Z, you can set the `trueZPress` parameter to true.
 
+### Enable Nunchuk support
+
+Nunchuk support is disabled by default as it can cause a number of issues if the
+i2c pins (pin 2 and 3 on Arduino Leonardo) are used for GPIO. To enable it, find
+the line `#define NUNCHUK_ENABLE false` at the top of HayB0XX.ino and change it
+to `true`.

 ## Troubleshooting
 
+### Controller not working with console or GameCube adapter
+
+- Make sure you are holding C-Down on plugin (if using default bindings).
+- If you are using an official adapter you will likely have to disable the
+  polling latency optimisation by passing in a polling rate of 0 to the
+  GamecubeBackend constructor.
+- If using pins 2 or 3 for your GameCube circuit, make sure Nunchuk support is
+  disabled
+
+### Joystick.h, nintendo.h, arduino_vector.h, and keyboard.h files are missing
 
+If the libraries are missing it's because you didn't download the release
+correctly. Do not click "download repo as zip" or "download source". Download
+the latest release artifact from the releases page.
