 ### Buttons
 
-There are up to three buttons at the top.  The most important is the
-*Enable*/*Disable* button, which switches the microphone on or off.
+There are up to two buttons at the top.  *Enable* starts the microphone
+when no local microphone stream is active.
 
 The *Mute* button mutes or unmutes the microphone; the microphone can be
 muted remotely by the hall moderator, but it cannot be unmuted remotely.
+To stop and release the local microphone stream, use *Turn microphone off*
+from the menu opened from your own name.
