Best way to transition from pack n play to crib?

At our 2 month old check up we were told its completely safe to move our LO to his crib. So we are going to try this weekend, since I go back to work in 2 weeks. We have started reading in his room to get him more familiar with it. Hes not a napper, im lucky if i get 2, 20 minute naps a day. Any suggestions on how to ease the transition? The doctor said it would be 2 or 3 days of going in every 5/10 minutes of checking on him but after that he will be okay. Any advice or tips/ tricks that worked for you?
