If you put your pizza an it and slide it in the oven there bottom of your pizza won’t cook.
Heat the stone in your oven for at least a half hour before putting your pizza on it.
Put the stone on the top rack so the top of the pizza gets hot, too, or put one stone above and one below.
Not sure it needs a half hour to heat up but yeah, preheating the stone along with your oven will give you a crispier crust.
I own a Emile Henry stone (not this one) and it’s great for pizza, bread, and biscuits.
If you have a broiler in the top of your oven, here’s the method I use for pizza:
Put stone on lowest position in oven and set the temperature to the highest setting. After it reaches temperature, give it 5 more minutes to heat the stone. This is a good time to top your pizza.
Switch your oven from bake to broil. You might have to wait a minute, or let a little heat out of the oven before your broiler will turn on. Once the broiler is on, slide the pie on to the stone.
Pizza should be done in around 6 minutes. Your oven may vary. Let it sit for about 5 before slicing.
