+h3. Quick Tour of +routes.rb+
There are two components to routing in Rails: the routing engine itself, which is supplied as part of Rails, and the file +config/routes.rb+, which contains the actual routes that will be used by your application. Learning exactly what you can put in +routes.rb+ is the main topic of this guide, but before we dig in let's get a quick overview.
