OSPF default route - ASA (doing NAT) to external ISP routers

I have an ASA doing NAT. I have two external routers, each on a different ISP/network. The routers are running BGP. I want to run OSPF between the ASA and the routers in order for the ASA to pick the default route based on BGP availability. Any idea where to start??

This would be as good a place as any to start. Have a read and come back if you have further questions
