 - A global sound volume slider
 - Volume sliders for each of the three audio channels mentioned above - VO, SFX, Music
 
+The sound plugin also supports customizing the step value (default = 0.1) of the volume sliders via the `stepOverride` param, this can be any value between 0 and 1. 
+
+e.g. if you'd like your volume slider to have only 4 volume levels you'd set it to 0.25 and the slider would use 0, 0.25, 0.5, 0.75, and 1.
