 Removing Servers
 ================
 
+Removing servers cannot be done whilst the uh-vpn-server service is running. The service needs to be stopped, then
+the associated token removed from the token store in ``/etc/uh-vpn-server/tokens`` and then the service needs to be
+restarted.
+
+This operation has the side effect of halting all VPN servers configured on the host machine.
+
+.. code-block:: bash
+
+    $> sudo service uh-vpn-server stop
+
+Now, the associated token needs to be removed from the token store:
+
+.. code-block:: bash
+
+    $> sudo nano /etc/uh-vpn-server/tokens
+
+This will bring up an editor prompt like so:

+
+Remove the token and save the file (Ctrl-X in nano). The service can then be restarted by issuing the command:
+
+.. code-block:: bash
+
+    $> sudo service uh-vpn-server start
+
+One should then check that the service is up and running:
+
+.. code-block:: bash
+
+    $> sudo service uh-vpn-server status
+
+The output should say **active (running)** as depicted below:
