+As an bonus feature, it's possible to use Nintendo Wii Remotes with Quack
+
+### Normal operation mode
+
+The Wiimote should be used in the vertical position. Pairing is done by using the red button in the battery compartiment
+After a successful pairing process, the Wiimote will play a chime and rumble for half a second
+
+Controls are as follow:
+- Directional pad is used to move the cursor
+- B is for click
+- A is for half-click (sticky mode)
+- ➕ and ➖ are for cursor speed
+
+LEDs meaning:
+1. slow speed cursor
+2. medium speed cursor
+3. high speed cursor
+4. pairing done
+
+The following remotes are supported in this mode:
+- Nintendo RVL-CNT-01 (First generation)
+- Nintendo RVL-CNT-01-TR (Wii Motion Plus)
+
+Others clones may or may not work. Extensions are not supported and should not be plugged in
+
+### Experimental operation mode
+
+The Wiimote driver inside quack only supports basic features. Using the Wiimote to move the cursor like on a real Nintendo Wii (aim at the screen) would require both Wii Motion Plus and a Light bar to work well. This is out of scope of this project
+
+That being said, if you want some extra difficulty on Arkanoid or Space Invaders, there is a "rough" X-Axis only motion mode
+
+The feature needs a calibration first. Put the Wiimote flat on a surface and then press the home button. The Wiimote will rumble and start calibrating. LEDs 1 to 3 will go off. Once the calibrating is done, the Wiimote will rumble again.
+
+Flipping the remote left or right will make the cursor move to that direction
+
+Press home again to go back to standard mode
