Sending Patches to games you build?

So let me explain kind of what I was thinking. First off this game is an online multiplayer game and in some rooms kids will be able to see each other but not in all rooms. As I add mini games I want to have the teachers and parents get notified of the updates via my website and then they can download the patch. I was reading that in 4.8 they have a patching system or something that helps send updates to the game.

I want to see if anybody has done it with the engine so far and if maybe there is a way to do this.

The C# thing is not a bad option but I do not understand how it works?
