 ^^^^^^^
 
 Ignores everything between ``{% comment %}`` and ``{% endcomment %}``.
+An optional note may be inserted in the first tag. For example, this is
+useful when commenting out code for documenting why the code was disabled.
 
 Sample usage::
 
     <p>Rendered text with {{ pub_date|date:"c" }}</p>
-    {% comment %}
+    {% comment "Optional note" %}
         <p>Commented out text with {{ create_date|date:"c" }}</p>
     {% endcomment %}
