Introduction to Ruby on Rails

The document introduces Ruby on Rails by summarizing what it is and how it works. Rails is a web application framework that uses the Model-View-Controller (MVC) pattern. It favors convention over configuration, including established folder structures, file naming, and other conventions that reduce complexity. Rails includes features like ActiveRecord for object-relational mapping, generators for rapidly building elements like models and controllers, and built-in support for test-driven development.
