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:files/activerecord/README_rdoc.html]. + +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:files/actionpack/README_rdoc.html]. + +== 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.
