easily to find a source term.

+Transifex integration
+=====================
+This module will add a link to the Transifex project in the translation view.
+The purpose of this module is to speed up translations of the main modules.
+
+To work, Odoo uses Transifex configuration files `.tx/config` to detec the
+project source. Custom modules will not be translated (as not published on
+the main Transifex project).
+
+The language the user tries to translate must be activated on the Transifex
+project.
