ASA basic setup

I need help setting up my ASA 5520. Its just a basic configuration, the outside it directly connected to my cable modem and the inside is connected to my internal network. I've never setup on of these before and I think the issue lies in my NAT config. When I hook it up I can connect to the ASA internally and it works but I can not get through to the internet on the outside interface. Any suggestions??
