pediatrician for baby

I'm a ftm! And I have no idea what I'm doing lol Those of you who are experienced moms, how do you go about finding a pediatrician? What should I look for? And after I do find "the one", do I just call up their office and tell them I want them to be my baby's doctor and they would know what to do? Help!!
Thank you so much! Your comments and insights have been very helpful!
