Did you know that Doctrine 2 is already very well documented? I've noticed recently that some people seem to think we don't have any documentation for it, and that upgrading will not be possible for many months to come.

We have an almost complete manual on Doctrine 2 which is the same concept of "Guide to Doctrine for PHP" for Doctrine 1. It covers all the core concepts of Doctrine 2 as well as information on how to get started, code examples, best practices, etc.

The Guide to Doctrine for PHP starts off with the following chapters...

• Introduction
• Architecture
• Configuration
• Basic Mapping
• ...and more

The following chapters have been completed and updated recently...

• Events
• Tools

We also have a cookbook with a few articles already too...

• Implementing ArrayAccess for domain objects
• Implementing the NOTIFY changetracking policy

We hope this helps you a little bit with getting started using Doctrine 2 and that you enjoy it! :)
