Question

1. Create a new controller called User. Create the following pages for
   it: index, register, login and logout. It’s just enough to use a
   generator script to acomplish this.

2. Add new items into the main menu: Register and Login. The main menu
   is defined in the application layout file
   app\views\layouts\application.html.erb. Notice that we are not yet
   adding a menu link to the index page at this stage.

3. Try out your application. If the new pages don’t work, restart
   Mongrel web application.

what is the second point? How should i do it?

I did this tutorial a few years ago. The second step is to add the links for the new actions you have generated: index, register, login and logout

Go to your application.html.erb and edit it:

  ...
  <div id="nav">
    <%= link_to_unless_current "Home",  :controller => "site", 
                                        :action => "index" %> | 
    <%= link_to_unless_current "About", :controller => "site", 
                                        :action => "about" %> | 
    <%= link_to_unless_current "Help",  :controller => "site", 
                                        :action => "help" %> |

    #include the new actions as the example below:
    <%= link_to_unless_current "Login", :controller => "user", 
                                        :action => "login" %> | 

 </div>

Also note that this tutorial is for Rails 2.3.9. I suggest you to take a look on his video about rails 3 and shopping cart: http://ecommerce2011.tumblr.com/post/11687504985/lecture-4-techniques-part-2-the-shop-on-rails
