What do I really have to know? Breathing is natural.
Breathing underwater is not natural. The effect on your physiology has to be understood. The skills need to be learned and practiced, assuming you have the ability.
I know that the tank has to be on, that the second stage regulator goes on the tank, and that the first first stage regulator is what goes in my mouth
Call me. I want to watch you attach the second stage to the tank and breathe from the 1st stage.
(well, at least when I am diving)... Just kick with your feet and enjoy it.
Up until something goes wrong ... which, sooner or later, it will.
