## Creating a Rails Application
You're new to Rails and would like to create an application.

1. Generating the starting app

  $ rails demo
  $ cd demo
  $ ls -p
    README config/ lib/ script/ vendor/ Rakefile db/ log/ test/ app/ doc/ public/ tmp/

2. Creating a controller

  $ script/generate controller Say

  This will generate several files. The file app/controllers/say_controller.rb is what we want at this point.

3. Creating an action

  In app/controllers/say_controller.rb:

  class SayController < ApplicationController
    def hello
    end
  end

4. Starting the server

  $ script/server

5. URL

  http://localhost:3000/demo/say/hello

  where
    http://        is the protocol
    localhost:3000 is the server and the port
    demo           is the app
    say            is the controller
    hello          is the action

6. HTML template

  In app/views/say/hello.html.erb

  <html>
    <head>
      <title>Hello</title>
    </head>
    <body>
      <h1>Hello</h1>
    </body>
  </html>
