At the bottom of this article you will find a number of resources to help you learn more about ruby on rails and related information, as well as links to some rails tutorials that will go into more depth than this document.

Before you start digging your feet into Ruby on Rails, you should understand exactly what it is.

Ruby on Rails is an advanced object-oriented Model-View-Controller application framework. If you did not fully understand the meaning of the previous sentence, you are going to need to put in some study time before you can jump into rails programming. Ruby On Rails is aimed at advanced programmers; jumping into it before you’re ready is likely to be very very hard. This tutorial should be easy enough for anyone to follow, but there’s a lot more to rails than you’ll be learning here.

This tutorial serves as a first step into ruby on rails development on Bluehost. The Model-View-Controller (abbreviated to MVC) design pattern is fairly straight-forward, it simply means that your program is split into three separate components: The Model, View, and Controller. The “Model” is your data, no matter how it is stored. If you are writing a blog, this is where all of your posts and comments would go. The “View” is your interface. In the case of Ruby on Rails, we are talking about the part that displays your HTML. The controller handles the business logic and ties the model to the view. MVC programming is beneficial for many reasons. From this point on, it is assumed you have an understanding of both object-oriented design and MVC and now you can get into how to develop rails applications on Bluehost.

A few additional notes before you start: First of all, you need to have SSH access enabled.
