it is pretty easy and I took two big potatoes I bought to do this before I found another full bag of big potatoes.You brush on peanut oil to cover the potatoes and it called for 1/2 tsp of coarse sea salt but I just have fine sea salt and I did not measure it I just shoot it out of the small holes in container onto the potatoes on both sides....preheat airfryer to 400degrees 200C and then put the two potatoes into air fryer and cook 400 for 60minutes....should have a good solid crust on potato and inside that is soft and smooth. I took a stick of unsalted butter out of fridge too so it will get a little bit softer in hour out at room temp....I still have 20min to go before I can eat one of the potatoes....I might just make both of them my dinner....but I do have a cooked on grill with sauce on it pork steak too so might eat one and then include the pork steak into the meal....just ate some mixed nuts and a bunch of fritos so I am not all that hungry now but the dinner will start after the potatoes are done....I could do one tomorrow as a twice baked potato with adding cheese and butter to inside of it then heat it up in the air fryer or the microwave I guess....
