 Group Administrators
 ====================
+
+Premium groups can have more than one administrator. This enables multiple user accounts
+to control all aspects of the group. This setup is particularly suited to environments where
+more than one person is responsible for VPN operations. For example, IT engineers within a
+company.
+
+To associate or remove an administrator one must first click the |settings_icon| icon next to the appropriate
+group in the `management page`_. After clicking, one is presented with a page displaying group administrators
+and billing information.
+
+Associating a new admin
+~~~~~~~~~~~~~~~~~~~~~~~
+
+To associate a new administrator to the group one must first click the "Associate New Admin" button at the
+base of the list of admins. One is then prompted for a user ID of the admin one wishes to associate. This can
+be found on their `profile`_ page. Once entered, click submit and the new administrator will have access to the
+group in their management page.
+
+Deleting an admin
+~~~~~~~~~~~~~~~~~
+
+It is also possible to remove administrators from a group. To do so, one needs only to click on the
+|delete_icon| icon next to the admin they wish to remove.
+
+.. note::
+    It is not possible to remove oneself from the list of admins, as doing so could potentially
+    leave the group with zero administrators.
