Well, I am looking for Dev documentation like the one at http://odoo-master.readthedocs.org/en/master/howtos/backend.html
I already start translate it
For those with opinion about it (like dev MUST work in english) you have the right to get one, but that post is not about opinion but about developing in french community.
@Ermin Trevisan: Please take the time to read, the Official doc and those at http://odoo-master.readthedocs.org/ are not the same but more complementary documentation and the doc at the seconde place is more complete. At rtdo they explain the Idea module and ask to do the academy module and the official doc explain the academy module.
