REST on rails

I just heard about REST capabilities of rails 1.1. Does anyone know a
good tutorial, or good article to begin with?

In the latest revision of Agile Web Development with Rails (beta book PDF) there are probably 10+ pages on it, it’s the best content I’ve seen on it.

In my latest app I’m using Restful Authentication [1] and crudgenerator2 [2] to try out Restful architecture.
