The documentation is now directly in the phpcr-odm repository

http://www.doctrine-project.org/projects/phpcr-odm.html

Git clone this repository.

Update the submodules (used for the doctrine theme)

git submodule update --init

Run

./bin/install-dependencies.sh

Run

./bin/generate-docs.sh

It will generate the documentation in PDF format into the build directory of the checkout.

Alternatively, you can go into en/ and type make to see what other formats you can generate.
