+Transifex
+---------
+
+All Invenio internationalisation and localisation efforts are happening on the
+`Transifex <https://www.transifex.com/>`_ collaborative localisation platform.
+
+You can start by exploring `Invenio project dashboard
+<https://www.transifex.com/inveniosoftware/invenio/dashboard/Invenio>`_ on
+Transifex.
+
+Invenio project consists of many resource files which can be categorised as
+follows:
+
+- ``invenio-maint10-messages`` contains phrases for Invenio 1.0 legacy release series
+- ``invenio-maint11-messages`` contains phrases for Invenio 1.1 legacy release series
+- ``invenio-maint12-messages`` contains phrases for Invenio 1.2 legacy release series
+- ``invenio-xxx-messages`` contains phrases for Invenio 3.0 ``invenio-xxx`` module
+
+We follow the usual Transifex localisation workflow that is `extensively
+documented <https://docs.transifex.com/>`_.
