Seriously... Moka Confusion

So I'm reading... fill the basket of a mokapot fully... fill it to over flowing... don't fill it all the way. Then in every combination with above you should and should not tamp, some say tamp it somewhat hard, some say soft, some say just enough to level it out...no real pressure... some say tamping is the devil.... heat on high, heat on medium...hell heat on low. But wait there's more. Heat the water before you connect everything... And make sure you tighten the top and bottom very tight... or not...very loosely... well kind of tight but not very... or really?

I've read threads, read instructions, watched videos... it's enough to make me give up coffee and go straight for the vodka.
