Knead it for 5 minutes. Put a little oil in the bottom of a big bowl, and roll the dough round in it so the surface is oily. Cover, and leave in a warm place to double in size, this usually takes about 2 hours.
Punch it down, divide into two and let the two pieces sit in a warm place, covered, for about twenty minutes.
Now they're ready to roll/shape into two 12" rounds, and add the toppings.
If using a stone, put it in the oven and preheat oven to 425F. If using a stone, let it stay at that temperature for another 5 - 10 minutes before putting anything in.
The pizzas take about 11 minutes to cook, you can turn on the broiler for another minute or so for a crispier top.
