This book is for developers who want to create their own Joomla! extensions. It is assumed you will have some basic PHP, HTML, and CSS knowledge, but you don't need any prior Joomla! programming experience.

Although this book starts out from scratch, it builds up to some more advanced topics that will interest experienced developers, such as integrating a third-party comments extension, so it is not just for beginners.

This book may also be useful to people that just want to make minor customizations to existing Joomla! extensions and build on the work of others in the open source spirit.
