+**WARNING: experimental !**
+
+Mapnik's PluginArchitecture supports the use of different input formats.
+
+This plugin supports reading WLANs found by running the [kismet](http://www.kismetwireless.net/) daemon. 
+
+
+# Installation
+
+There needs to be a running _kismet_server_ process with activated GPS support before starting mapnik. 
+
+
+# Parameters
+
+| *parameter*       | *value*  | *description* | *default* |
+|:------------------|----------|---------------|----------:|
+| host                  | string       | host where the kismet daemon is running | |
+| port                  | integer      | port of the kismet daemon | |
+| extent                | string       | max extent of the kismet returned wlans | |
+| encoding              | string       | internal file encoding | utf-8 |
+
+
+# Example
+
+See next an example XML file to render WLAN icons on the map.
