 Usage
 =====
 In all cases, you must first `configure YouTube Live <https://www.youtube.com/live_dashboard>`_.
 Then your chosen input will stream live on YouTube Live.
 
+In the non-file streaming scripts, you can specify your video/audio device if desired at the top of the script.
+You can find device names with commands like:
+
+* Windows: ``ffmpeg -list_devices true -f dshow -i dummy``
+* Mac: ``ffmpeg -f avfoundation -list_devices true -i ""``
+* Linux: ``v4l2-ctl --list-devices``
