+		Warning: 'resin promote' requires an openssh-compatible client to be correctly
+		installed in your shell environment. For more information (including Windows
+		support) please check the README here: https://github.com/resin-io/resin-cli
+
+		Use this command to promote your device.
+
+		Promoting a device will provision it onto the Resin platform,
+		converting it from an unmanaged device to a managed device.
+
+		Examples:
+
+			$ resin local promote
+			$ resin local promote --port 22222
+			$ resin local promote --verbose
