Download the Disney land app, once your are inside the park after the ticket check activate your fast pass. The app only lets you book one ride at a time, so always book the ride that is the earliest for u. The time shown in the app for the ride, is the time for you to go to fast pass line, not before not after. It is just like making an appointment for the fast pass line for the ride.
1. You can only hold 1 fastpass at a time so only get fastpasses for long wait time rides. 2. Make sure to get a fastpass early on in the day as some rides run out of fastpasses for the remaining day quicker than others.
You go into the lane that would say "fastpass lane", and you would scan your fastpass and they would let you go into the line
