##What is Rails?
Rails is an open source web application framework written in Ruby. It is a full-stack framework that has been optimised for programmer happiness and sustainable productivity. It emphasises the use of well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), the active record pattern, and model–view–controller (MVC).
Extra: David Heinemeier Hansson (DHH) is the creator of Rails, having extracted it from his work on Basecamp. He first released Rails as open source in July 2004.
