Welcome to the Instant Pot life! I bought the 6 qt one for DH and me as we are retired and like suern3, love left overs.
I don't know about the recipes for the 3 qt but you will find lots of knowledge online about what's what.
Their is a Jackie and Amy that post regularly on line and they have some delicious looking recipes. They are now working for IP or with IP.
You will love the hard boiled/steamed eggs.
