Getting Started with the Wright Framework
If you are new to Joomla, then it is best to take some time to learn the basics of how to manage your site. The first place to visit is http://docs.joomla.org. Here you can follow some of the introductory documentation to get you started.
Joomlashack University, the #1 online learning site for Joomla, has an extensive set of lessons, courses, and video tutorials. Take these classes and you are sure to learn Joomla the "correct" way. New content is added regularly.
HTML is the language of the web. It is a fairly basic, yet very powerful language that holds the information in almost all web pages. There are many resources online to learn about HTML, as well as many books or video series. Often these books are tied to CSS learning as well.
PHP is the programming language that Joomla is built upon. It is a very popular and practical language, and is one of the easiest to learn. That said, it can also be easy to learn the basics and accidentally break more complex code. We recommend avoiding simple 'tweaking' to any PHP code unless you are properly trained in the language.
