Your phone should automatically try to connect to Facebook through the LIVE screen.

If you can't get a connection it should let you know

If you see the Blue GO LIVE Button come up, you will be able to start recording a LIVE video, but before you go live....add a description to what you are about to record.

Step Four: Click on the "Describe your live video..."

I added this description

Step Five: now click on the Go LIVE button
