Ruby on Rails Intro
Ruby on Rails is a web development framework written in the Ruby programming language. It uses the MVC architecture, with models, views, and controllers, and follows RESTful conventions. The document lists Truong Vo as a software engineer and provides an introduction to Ruby on Rails, describing its MVC structure and RESTful routing, and recommends learning resources like books and websites for working with the framework. It also shares examples of web applications built with Rails.
