PHPCR ODM is listed on the Doctrine website:
build doc in this repository:
The next step would be to collect all the various documentation flying around and convert them to reST format:
http://melp.nl/2011/07/symfony2-phpcr-doctrine2-jackalope-recipe/ (needs to be made Symfony2 unspecific)
http://www.craftitonline.com/2011/07/first-symfony2-cmf-based-cms-pagesbundle/ (needs to be made Symfony2 unspecific)
http://cmf.symfony.com/slides.html (needs to be made Symfony2 unspecific)
any other articles flying around?
of course we should also reference PHPCR related docs
