Documentation
The most important resource for learning any open source technology is the documentation that it comes bundled with. This section introduces you to the available documentation for MODx.
There are three kinds of documentation available:
Official documentation
Community-driven documentation
Combined
Official documentation
The official documentation for MODx is available from the official MODx site at http://MODxcms.com/documentation.html. The official documentation tries to contain as much text as possible to cover everything about MODx. However, due to the rapid level at which changes happen, and the process involved in making documentation official, the official documentation does not cover everything. You can be assured that whatever is covered in there is free from error, and can be a very good resource to start with, but, as you progress with MODx, you will find that there are other forms of documentation that are more interesting.
