+Generating the POI Markers
+==========================
+
+genPOI.py
+---------
+
+In order to actually generate the markers and add them to your map, the script 
+genPOI.py must be run. For example::
+
+    genpoi.py --config=/path/to/your/config.file
+
+.. note::
+    Markers will not be updated or added during a regular overviewer.py 
+    map render!
+
+This will generate the necessary JavaScript files needed in your config file's
+outputdir.
+
+Options
+-------
+
+genPOI.py has a single option:: --config. You should use the same configfile as 
+used for your normal renders.
