First thing....take it back and get a 6 qt...you'll find it more useful...and then just google instant pot recipes..you've heard of all the uses written in the post. Personally, I use mine at least 3 times a week...spaghetti squash-10 min., pork loin with balsamic vinegar, apple and honey sauce-3 min, risotto-snap of your fingers...you'll want the 6 qt to make soups and freeze half for later. Oatmeal-wonderful. Hard boiled eggs 5 min.
The safety devices on these things are phenomenal and an electric pressure cooker cooks at a slightly lower temp with takes away some of the intensity...Trust me and all the others here who have given you advise...get the 6 qt and just begin...You tube has thousands of videos on this...just do it! you'll never look back.
