+===== Changing the sounds =====
+Changing the sounds requires modifications to the firmware. The code for the sounds is located in modules/src/sound_cf2.c.
+A sequences is defined in the .notes member of the Melody struct. The notes are defined as tuples of a note (pitch) and duration. A sequence must be ended with the end marker.
+The effects are defined in the effects array. Each entry takes a function to call and related parameters.
+To add a new melody, use the melodyplayer function for the .call member and assign your Melody struct to the .melody member.
