Hey @notanescaperoom 
I don’t have all the steps to create this site on the eLearning Hub. Some steps are there, for example, how to make a one page app, using set states and other things like that.
I will be adding how to do a ‘room’ feature soon on the eLearning Hub as well.
For updating the player count, when the user joins a room, I add them to the room’s list of users. That way, I can display it to the host as well as give the host a count of how many users are in the room.
Does that make sense? I hope that helps a bit.
