-Actually I think greenstone 3 version is completely different??? **TODO**
+Grouping in Greenstone 3 is controlled by the groupConfig.xml file, found in a site folder alongside the siteConfig.xml file. For example, in /home/user/greenstone3/web/sites/localsite/groupConfig.xml.
+By default, there are no groups.
+Add hierarchy and groupDescriptions elements to add groups to your library.
+Describe your structure inside a hierarchy tag as shown in the examples below.
+Hierarchies can contain groups and/or collections. Groups can contain other groups and/or collections.
+The order they are listed is the order they will appear on the home page.
+Describe your groups in groupDescriptions element as shown in the example below.
+Without a matching group element in groupDescriptions, a group will display its name.
+If a collection is not mentioned in the hierarchy or as part of a group it will be listed on the main
+home page after the specified groups and collections.
+Example 1: this example puts a few Greenstone demo collections into some groups. The home page
+will display the demo group plus any unlisted collections. The demo group home page will display its two subgroups; their home pages will display their list of collections.
+<code>
+<groupConfig>
+  <hierarchy>
+    <group name="demo">
+      <group name="standard">
+	<collection name="solr-jdbm-demo" />
+	<collection name="lucene-jdbm-demo" />
+      </group>
+      <group name="dec">
+	<collection name="bibtex-e"/>
+	<collection name="dls-e"/>
+	<collection name="garish-e"/>
+	<collection name="isis-e"/>
+      </group>
+    </group>
+  </hierarchy>
+  <groupDescriptions>
+    <group name="demo">
+      <title>Demo Collections</title>
+      <description>Collections for demonstration purposes, provided by the Greenstone project.</description>
+      <shortDescription>Greenstone demonstration collections</shortDescription>
+      <backgroundImage>/images/Group3.jpg</backgroundImage>
+    </group>
+    <group name="standard">
+      <title>Standard Demos</title>
+      <description>These collections are the standard demonstration collections that come with a Greenstone binary release.</description>
+      <shortDescription>Demonstration collections that come with the Greenstone binary.</shortDescription>
+    </group>
+    <group name="dec">
+      <title>Documented Example Collections</title>
+      <description>These documented example collections describe how they are constructed on their about page. Useful for learning about different Greenstone features.</description>
+      <shortDescription>Collections that describe how they were built.</shortDescription>
+    </group>
+  </groupDescriptions>
+</groupConfig>
+</code>
+Example 2: If you want to put your collections into a specific order, you can list them in the hierarchy. Any unmentioned collections will be listed at the end. This example has no groups, but is a way of specifying which order you want the collections to appear on the home page.
+<code>
+<groupConfig>
+  <hierarchy>
+    <collection name="solr-jdbm-demo"/>
+    <collection name="lucene-jdbm-demo"/>
+    <collection name="paradise-gardens"/>
+  </hierarchy>
+</groupConfig>
+</code>
