Post some pictures when you make some.
Tip: You will need to turn the pizza often so you don't burn in one spot.
Take a visit to the Pizza Making forum.
You can find recipes, and experiences of others that have your oven.
They have dough generator formulas there as well.
As you suggested I joined the other forum to read up all the things I don't know and did my first attempt on my Ooni Fyra today.
The roaring fire going when I took the front off right before I slapped a pizza in it.
Ended up at one point getting a reading over 1000 degrees but was trying to be in the 950ish range.
Below are a couple of the pizzas I made. Turned out better then I expected for my first time using it.
Biggest mistake, besides slightly overdone, was using a store bought sauce on them. Way too much salt in it so I will make my own next time.
