+# Gadgetbridge Twist Control
+
+Control your music app (e.g. MortPlayer Music [a folder based, not tag based player] ) that handles multiple play-commands (same as using a single-button-headset's button to change songs) on your Gadgetbridge-connected phone.
+- Activate counting for 4 seconds with a twist (beeps at start and end of counting) 
+- twist multiple times for:
+ play/pause (1),
+ next song (2),
+ prev. song (3),
+ next folder (4),
+ prev. folder (5),
+ reset counter (6) 
+- the command to be sent is shown in green
+- Volume up/down is controlled by BTN1/BTN3 presses
