Problems about iOS10 ReplayKit Live Broadcast

Hi everyboady, the new iOS10 is coming. However, there is almost no document about the live broadcast in ReplayKit. I’m a newbie, I have no idea about how to build such a live broadcast app from scratch. Can somebody post some articles about this new feature? For example, I can record my iOS device screen and upload the video data in real time to my computer, which serves as a local server.
