+===============
+Message forward
+===============
+
+This module was written to extend the functionality of mails to support
+forwarding them to another contact or database object.
+
+* **To another object of the database:** All its followers are notified
+  according to their settings.
+
+* **To other contacts:** They recieve the forwarded message according to the
+  usual notification rules of Odoo.
+
+Configuration
+=============
+
+When installed, this module allows forwarding to a limited selection of
+database models, that will get automatically updated when you install other
+modules.
+
+This list can be customized by a user that has *Technical Features* permission.
+To do it:
+
+* Go to *Settings > Technical > Database Structure > Referenceable Models*.
+
+* Any model there with *Mail forward target* enabled will appear in the list of
+  models that can get forwarded messages.
+
+  * If you want to *remove* a model from the list, it's usually better to just
+    *disable* its check box instead of deleting it, because that record might
+    be used by other modules.
+
+Usage
+=====
+
+To use this module, you need to:
+
+* Go to any view that has a message thread.
+* Press *Forward* (the button with a curved arrow pointing to the right).
+* Modify the subject if you wish.
+* If you want to forward the message to an *object*, choose it from the
+  selector.
+* If you want to forward the message to some partner(s), add them in the
+  selector.
+* Modify the message if you want.
+* Add attachments if you want.
+* If the message contains attachments, you can turn on the *Move attachments*
+  option, and those will get attached to the new object.
+
+  You will need to install the *document* module and have at least *User*
+  permissions for *Knowledge* to see the effect.
+
+.. info::
+    Technical note: Internally, forwarded messages are modified copies of
+    original ones, but attachments are references to the exact originals to
+    avoid duplicating disk space. Keep that in mind when managing permissions.
