+            <h3>Explanation</h3>
+            In it's almost most basic configuration, Mapbuilder can also be used to simply put a WMTS map
+            plus an overview map in a web page.<br/>
+            The configuration for this page consists of a single 
+            model (a OWS Context document) and three widgets (MapPaneOL for the map, PanZoomBar for OpenLayers controls and OverviewMap).
+            See the <a href="../interactive/index.html">Interactive Map Viewer</a> to for an example of an interactive map, 
+            as well as some of the more common ways to work with MapBuilder.

For example, if a map zoom level of 1 corresponds to your cache level zero, you would supply a -1 zoomOffset (and set the maxResolution of the layer appropriately).
