+== 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 (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.
+
+The View layer is composed of "templates" that are responsible for providing
+appropriate representations of your application's resources. Templates
+can come in a variety of formats, but most view templates are \HTML with embedded Ruby
+code (.erb files).
+
+The Model layer represents your domain model (such as Account, Product, Person, Post)
+and encapsulates the business logic that is specific to your application. In \Rails,
+database-backed model classes are derived from ActiveRecord::Base. Active Record allows
+you to present the data from database rows as objects and embellish these data objects
+with business logic methods. Although most \Rails models are backed by a database, models
+can also be ordinary Ruby classes, or Ruby classes that implement a set of interfaces as
+provided by the ActiveModel module. You can read more about Active Record in its
+{README}[link:/activerecord/README.rdoc].
+
+The Controller layer is responsible for handling incoming HTTP requests and providing a
+suitable response. Usually this means returning \HTML, but \Rails controllers can also
+generate XML, JSON, PDFs, mobile-specific views, and more. Controllers manipulate models
+and render view templates in order to generate the appropriate HTTP response.
+
+In \Rails, the Controller and View layers are handled together by Action Pack.
+These two layers are bundled in a single package due to their heavy interdependence.
+This is unlike the relationship between Active Record and Action Pack, which are
+independent. Each of these packages can be used independently outside of \Rails. You
+can read more about Action Pack in its {README}[link:/actionpack/README.rdoc].
+
+== Getting Started
+
+1. Install \Rails at the command prompt if you haven't yet:
+
+    gem install rails
+
+2. At the command prompt, create a new \Rails application:
+
+    rails new myapp
+
+   where "myapp" is the application name.
+
+3. Change directory to +myapp+ and start the web server:
+
+    cd myapp; rails server
+
+   Run with <tt>--help</tt> or <tt>-h</tt> for options.
+
+4. Go to http://localhost:3000 and you'll see:
+
+    "Welcome aboard: You're riding Ruby on Rails!"
+
+5. Follow the guidelines to start developing your application. You may find the following resources handy:
+
+* The README file created within your application.
+* {Getting Started with \Rails}[http://guides.rubyonrails.org/getting_started.html].
+* {Ruby on \Rails Tutorial}[http://ruby.railstutorial.org/ruby-on-rails-tutorial-book].
+* {Ruby on \Rails Guides}[http://guides.rubyonrails.org].
+* {The API Documentation}[http://api.rubyonrails.org].
