+All upstream OpenStack documents in ``openstack-manuals`` and project
+repositories use ``master`` branch and can have stable branches depending
+on release models and maintaining documents in different project teams.
+Cross-project liaisons are strongly encouraged to communiticate with I18n

+the target in I18n team and when translators start to translate stable
+documents.
