+  4.5. Configuration of spatial printing
+  ======================================
+
+It is possible to add a polygone-layer in QGIS, which is queried in the Web-Client for spatial related printing-information. You could e.g. add a layer with regional information as name of the region, phone number and other contact details of the responsible administration. To do this, follow-up these steps in QGIS:
+1. The layer providing spatial related printing-information has to be named 'print'
+2. The polygone-geometry field of the layer has to be named 'geometry'
+2. Use the attribute-title of the layer in the print template as 'Item ID' (de: 'Elementkennung')
+3. To hide the layer 'print', you could exclude it from the WMS-Capabilities (QGIS: project-settings->ows server-> WMS-Capabilities)
+4. The layer has to be published in the WFS-Capabilities
+
+Now the QGIS-client sends the spatial information (attribute-titles of the layer 'print') to the server and there the corresponding item will be filled in when generating a .pdf-document. For the spatial query, the center of the map is being used.

   5. URL Rewriting
