+# Geoserver FAO style
+
+The `fao_areas` layer is served as a Geoserver `wms` layer.
+
+For `geowebcache` to be running under `/wms` routes, the `WMS` caching direct integration must be setup:
+https://docs.geoserver.org/stable/en/user/geowebcache/webadmin/defaults.html#enable-direct-integration-with-geoserver-wms
+
+The style (named `FAO style`) is defined as the following SLD:
