+
+For example:
+

+Known issues / Roadmap
+======================
+
+* This custom html is not translatable, so as a suggestion, you can define
+  the same text in several languages in several lines.
+
+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>
