Using FourSquare API in a Rails App

Question

Anybody have any good resources that might be helpful in trying to integrate the FourSquare API into a Rails app? I'm specifically looking for a good tutorial. There doesn't seem to be much out there yet. There are a few ruby gems, but they are pretty bare bones and I need a bit more hand-holding.

Here is a resource that I've found so far:
http://tedgrubb.com/

Stack Overflow won't let me include a second hyperlink, but you can also google: Foursquare ruby gem for another resource.

I have not done much work with APIs in the past, but I am very comfortable with Rails. What I need is a little better sense of exactly where all the pieces fit. A basic tutorial is what I'm looking for.

Thanks.
