Cisco ASA and Cisco 3600 Router

I would like to ask another question. Our Company bought an ASA 5505. we connected a cisco 3600 router to interface 6. Interface 0 is the outside (Internet) interface. My question is how should we configure the ASA to enable a pc behind the router to access the internet.
