Looking for information on wills

I'm looking into information online about wills, and was just wondering if anyone knew of a good place to look for that sort of thing? I want to create a page at Family Caregiver Info for how to go about setting up wills and what is needed to create one and get it properly notarized and all that. Right now I don't know anything about wills, so this is going to be a interesting exploration in just how the things work and what goes into creating one.
