+Installing SSL on the Deis Routers
+----------------------------------
+
+You can also use the Deis routers to terminate SSL connections.
+Use ``deisctl`` to install the certificate and private keys:
+
+.. code-block:: console
+
+    $ deisctl config router set sslKey=<path-to-key> sslCert=<path-to-cert>
+
+If your certificate has intermediate certs that need to be presented as part of a
+certificate chain, append the intermediate certs to the bottom of the sslCert value.
+
+.. note::
+
+    To secure all endpoints on the platform domain, you must use a wildcard certificate.
