Well, you said

Contributing is not easy when you don't know the repo.

btw, shouldn't the base repo be moved from your account to Doctrine rather than forking it and makin gthe fork the main repo ? It can be quite confusing for contributors (experience talking from FOSUserBundle where it took several months for people to get used to it properly)
