Joomla! Documentation™

As a developer you are tasked with altering or extending the functionality of Joomla! or one of its extensions. You will be proficient in a range of programming languages, including PHP, but may be less familiar with such things as JavaScript or CSS. If you are new to Joomla! you will need information about the Joomla! Framework API and how to use it and will probably make extensive use of best practice example code.
