+Adding Arbitrary Content
+========================
+
+Additional content can be included in arbitrary sections that get
+added to the end of the GM notes output. In addition to the attributes
+described above, suitable extra attributes in the notes (``.py``) file
+will be rendered as a new section, with a heading based on the name of
+the attribute and a body with the content parsed as restructured
+text. Attributes that begin with an underscore ("_") or those that are
+not a string will be ignored.
+
+For example, the following entry will be rendered as a new section
+with the heading "The Bar Fight":
+
+.. code-block:: python
+
+    the_bar_fight = (
+         "If the characters decide to go to the *Alliance Friendly Bar*, "
+	 "they will probably have to fight their way out against 5 enemies "
+	 "(3 Veteran, 2 Soldier)."
+    )
