# Using the Map Preview

The Map Preview tool is used to quickly preview a layer that has been configured in GeoServer. It is based on the OpenLayers library which is a great tool for visualizing layers via WMS. This section covers the use of the Map Preview.

1. Navigate to the GeoServer Welcome Page.

2. From the Welcome page navigate to the Map Preview by clicking the Demo link, followed by the Map Preview link.

   Note

   The Map Preview contains a list of all layers currently published by GeoServer. A layer can be previewed in a variety of formats like KML and GeoRSS. The default is an OpenLayers map.

At this point the shapefile added in the previous section has been verified with the map preview. In the next section the default style for the layer will be changed and the map preview will once again be used to verify.
