there are about 4500 different docuements covering HSRP and other first hop redundancy protocols available at cisco.com.

First thing, you will need a means for the two routers to share a common subnet, some sort of switch between the two.

Second, based on the version of code you are running, consult the appropriate configuration guide for the specifics.

here is a sample of the document you need:
