 With this module you can set a custom unsubscribe link appended at the bottom
 of mass mailing emails.
 
+It also displays a beautiful and simple unsubscription form when somebody
+unsubscribes, to let you know why and let the user unsubscribe form another
+mailing lists at the same time; and then displays a beautiful and customizable
+goodbye message.

 Known issues / Roadmap
 ======================
 
+* This needs tests.
 * This custom HTML is not translatable, so as a suggestion, you can define
   the same text in several languages in several lines.
 
-For example:
+  For example:
 
 .. code:: html
 
   <small>[EN] You can unsubscribe <a href="%(url)s">here</a></small><br/>
   <small>[ES] Puedes darte de baja <a href="%(url)s">aquí</a></small>
 
+* If you use the ``website_multi`` module, you will probably find that the
+  views are not visible by default.
+* This module adds a security hash for mass mailing unsubscription URLs, which
+  makes to not work anymore URLs of mass mailing messages sent before its
+  installation. If you need backwards compatibility, disable this security
+  feature by removing the ``mass_mailing.salt`` system parameter. To avoid
+  breaking current installations, you will not get a salt if you are upgrading
+  the addon. If you want a salt, create the above system parameter and assign a
+  random value to it.
+* Security should be patched upstream. Remove security features in the version
+  where https://github.com/odoo/odoo/pull/12040 gets merged (if it does).
