That is not the only thing you can do with it. You can use it as a browser to visualize HTML pages and FTP commands to upload files to your FTP server.
You can also program other programming language customizable syntax based.
And if you are not an experienced programmer, it allows you to include some elements (HTML and CSS) directly with shortcuts without having to know how to edit the tags, and a lot of options that will make easier your work.
