===Header===
A header call to this template must be the first usage of this template.
<pre>{{nav|header|DQI|{{DQ}}|title=Ninjas|class=navMainSeries}}</pre>
*header: A required parameter which marks this as the start of a navigation bar. This parameter must be the first parameter. It does not take a value.
*template: A required parameter specifying the name of the template containing the nav template calls.  This parameter is a value only.  The parameter must be the second parameter.  It is used in the [[Template:tnav|tnav]] template in order to provide easy access to editing and discussion of the parent template.
*titlelink: A required parameter specifying the name to be displayed as the title of the navigation bar. This parameter must be the third parameter.  If a title parameter is not specified, this parameter becomes both the title link destination and the actual title.
*title: An optional parameter for specifying a title other than the name of the titlelink parameter.  Useful when you want the title to link to a category page.
*class: An optional parameter for specifying a class name which will alter the colors/styles of the navigation bar.  By default, the navMainSeries class is used. This parameter must come after the 3 required parameters.
