Great entry point for PathFinder! It not only goes through and explains each piece of the game, but also has tons of information, player journals and emphasizes how to use it in Foundry as well.
Encounters are interesting as they have different styles (unavoidable, avoidable, traps, "recommend you be quiet" etc.)
Comes with a few pre-made characters, I made some extra and allowed my players to swap out classes in between battle so they could get an idea of how different things played.
