The USAPA has provided a great summary of the full set (68 pages) of IFP rules. The USAPA has adopted the IFP tournament rules to ensure consistency whenever playing pickleball.
In general, there is a lot to know about the rules of pickleball. For many, the hardest part is actually un-learning rules and habits from other racket sports. I would recommend that you start with the summary and delve into the rulebook as questions arise while you play.
