Previously we noted that [localhost:3000/products](http://localhost:3000/products) was linked to the view `app/views/products/index.html.erb` through a route in our `config/routes.rb` file. Open the `index.html.erb` view now in a text editor (i recommend sublime text 2 for mac). Make sure your rails server is started (`$ rails server`) and visit [localhost:3000/products](http://localhost:3000/products) in your browser.
