Cmera Scene Overlays

I’ve scene it done before, so I know it’s possible, but I have no idea where to start. What I am hoping to do is have the information for my game that the camera will display located on scene B, but the game to happen on scene A. I need the camera to view both at the same time. Thanks.

add a camera in scene B too (the “information” should appear in the camera view)?!
Then in scene A add an empty with “Always Sensor -> AND -> Add Overlay Scene Actuator - Scene B”

Okay, thanks.
