The JOE Text Editor
We (the developers) like to use 'joe' among the many different editors available for *nix. You are welcome to use any editor, including vi or emacs, or even nano. One of the benefits of joe is it's visual delineation for HTML and PHP code.
Use of Joe is optional, but from here on in, this tutorial will assume you use Joe as your text editor.

sudo apt-get install joe
