 		Setting up a WebRTC connection between two peers may not seem a trivial task, but it can be broken down into 3 main steps:
-		- The peer that wants to initiate the connection ([code]A[/code] from now on) creates an offer and send it to the other peer ([code]B[/code] from now on).
-		- [code]B[/code] receives the offer, generate and answer, and sends it to [code]A[/code]).
-		- [code]A[/code] and [code]B[/code] then generates and exchange ICE candidates with each other.
-		After these steps, the connection should become connected. Keep on reading or look into the tutorial for more information.
