+Manage the Controller
+=====================
+
+The following documentation will help you get set up with managing your Deis PaaS
+controller to your liking.
+
+Sending Logs to a Remote Syslog Server
+--------------------------------------
+
+You can forward messages from Deis's syslog server to another remote server hosted outside
+of the cluster. This is used in a number of cases:
+
+- there is a legal requirement to consolidate all logs on a single system
+- the remote server needs to have a full picture of the cluster's activity to perform
+  correctly
+
+In our case, you can forward all messages from your Deis cluster to your remote syslog
+server by setting two keys in :ref:`Discovery`. SSH into your controller and run the
+following commands:
+
+.. code-block:: console
+
+    $ etcdctl set /deis/logger/remoteHost <your_remote_syslog_hostname>
+    $ etcdctl set /deis/logger/remotePort <your_remote_syslog_port>
