pizza without burnt crust in oven?

hi! planning on making pizza tomorrow and i have a few questions. recently i made a grilled cheese using the oven, and because all of the heat is coming from below (it's a gas oven) the bottom part of almost everything you put in turns really dark before the top starts to brown. i bought the dough from a grocery store, and i do not have an oven steel. what would be the best way to get a pizza that's not burnt on the bottom and has melted cheese on top? do i put it on the upper rack? use multiple sheets of baking paper? any help would be greatly appreciated :) (other tips regarding how to get the best result from store bought dough without an oven steel too!)
