Can you please explain (as simple as possible) how

Can you please explain (as simple as possible) how the program works? I think I heard it is structured similar to a multilevel program...such as, those who get in early and sell get paid on what they sell and also paid some from what those under them sell too? What exact product or products? I was on one of the calls at the beginning of all of this, but haven't had a chance to be filled in...Thanks!
