 == Welcome to Rails
 
 Rails is a web-application framework that includes everything needed to create
-database-backed web applications according to the Model-View-Controller pattern. 
+database-backed web applications according to the {Model-View-Controller (MVC)}[http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller] pattern.
 
 Understanding the MVC pattern is key to understanding Rails.  MVC divides your application
 into three layers, each with a specific responsibility.

-h4. The Rails Generation: Generators
-
-INFO: For a good rundown on generators, see "Understanding Generators":http://wiki.rubyonrails.org/rails/pages/UnderstandingGenerators. A lot of its material is presented here.
-
-Generators are code that generates code. Let's experiment by building one. Our generator will generate a text file.
-
-The Rails generator by default looks in these places for available generators, where Rails.root is the root of your Rails application, like /home/foobar/commandsapp:
-
-* Rails.root/lib/generators
-* Rails.root/vendor/generators
-* Inside any plugin with a directory like "generators" or "rails_generators"
-* ~/.rails/generators
-* Inside any Gem you have installed with a name ending in "_generator"
-* Inside any Gem installed with a "rails_generators" path, and a file ending in "_generator.rb"
-* Finally, the builtin Rails generators (controller, model, mailer, etc.)
-
-Let's try the fourth option (in our home directory), which will be easy to clean up later:
-
-<shell>
-$ mkdir -p ~/.rails/generators/tutorial_test/templates
-$ touch ~/.rails/generators/tutorial_test/templates/tutorial.erb
-$ touch ~/.rails/generators/tutorial_test/tutorial_test_generator.rb
-</shell>
-
-We'll fill +tutorial_test_generator.rb+ out with:
-
-<ruby>
-class TutorialTestGenerator < Rails::Generator::Base
-  def initialize(*runtime_args)
-    super(*runtime_args)
-    @tut_args = runtime_args
-  end
-
-  def manifest
-    record do |m|
-      m.directory "public"
-      m.template "tutorial.erb", File.join("public", "tutorial.txt"),
-        :assigns => { :args => @tut_args }
-    end
-  end
-end
-</ruby>
-
-We take whatever args are supplied, save them to an instance variable, and literally copying from the Rails source, implement a +manifest+ method, which calls +record+ with a block, and we:
-
-* Check there's a *public* directory. You bet there is.
-* Run the ERB template called "tutorial.erb".
-* Save it into "Rails.root/public/tutorial.txt".
-* Pass in the arguments we saved through the +:assigns+ parameter.
-
-Next we'll build the template:
-
-<shell>
-$ cat ~/.rails/generators/tutorial_test/templates/tutorial.erb
-I'm a template!
-
-I got assigned some args:
-<%= require 'pp'; PP.pp(args, "") %>
-</shell>
-
-Then we'll make sure it got included in the list of available generators:
-
-<shell>
-$ rails generate
-...
-...
-Installed Generators
-  User: tutorial_test
-</shell>
-
-SWEET! Now let's generate some text, yeah!
-
-<shell>
-$ rails generate tutorial_test arg1 arg2 arg3
-      exists  public
-      create  public/tutorial.txt
-</shell>
-
-And the result:
-
-<shell>
-$ cat public/tutorial.txt
-I'm a template!
-
-I got assigned some args:
-[["arg1", "arg2", "arg3"],
- {:collision=>:ask,
-  :quiet=>false,
-  :generator=>"tutorial_test",
-  :command=>:create}]
-</shell>
-
-Tada!
