How To Install Ruby on Rails on Ubuntu

• Ruby on Rails, often simply Rails, is an open
  source web application framework which runs on
  the Ruby programming language.
• It is a full-stack framework it allows creating
  pages and applications that gather information
  from the web server, talk to or query the
  database, and render templates out of the box.
• As a result, Rails features a routing system that
  is independent of the web server.
• Ruby on Rails emphasizes the use of well-known
  software engineering patterns and principles,
  such as active record pattern, convention over
  configuration (CoC), dont repeat yourself (DRY),
  and model/view/controller (MVC).

  Ubuntu 12.04 LTS, 13.10 and any future releases.
