Last night the Doctrine ORM for PHP book became available on the Amazon website. This is our first official piece of published documentation and we are very excited and proud to see this.

If you are an existing or new Doctrine user, it is much appreciated if you purchase a copy. Since Doctrine is an open source project we don't make any money directly from it. Doctrine is all possible because of the contributors and the companies that fund it, like Sensio Labs. So it is a very nice gesture, even if you are already a Doctrine expert, to purchase a copy of the book to show your appreciation and support for the project.
