+## Creating a menu based on indexes
+
+Hugo can generate menus based on indexes by iterating and
+nesting the index keys. This can be used to build a hierarchy
+of content within your site.
+
+To have hugo create the menu, simply create a template in chome
+called menu.html, then include it using the 
+`{{ template "chrome/menu.html" . }}` syntax.

+#### Example menu.html file
