This is a small Ruby tutorial that should take no more than 20 minutes to complete. It makes the assumption that you already have Ruby installed. (If you do not have Ruby on your computer install it before you get started.)

Ruby is a programming language from Japan which is revolutionizing software development. The beauty of Ruby is found in its balance between simplicity and power. You can type some Ruby code in the editor and use these buttons to navigate: Run → Executes the code in the editor; Copy → Copies the example code to the editor
