-        <p>Whilst tags are great at collecting datasets together, there are
-        occasions when you want to restrict users from editing a collection.</p>
-        <p>A group can be set-up to specify which users have permission to add or
-        remove datasets from it.</p>
+        <p>Groups allow you to group together datasets under a organisation (for example, the Department of Health) or topic (e.g. Transport, Health) so make it easier for users to browse datasets by theme.</p>
+        <p>Groups also enable you to assign roles and authorisation to members of the group - i.e. individuals can be given the right to publish datasets from a particular organisation.</p>
