This document discusses REST and routing in Rails 3.1. It explains that REST uses HTTP methods like GET, POST, PUT, DELETE to manipulate and represent resources. Rails scaffolds generate default RESTful routes and actions for basic CRUD. The hands-on section demonstrates generating a Photo scaffold, migrating the database, and using rake routes to view the default RESTful routes.
