+            ProxyProtocol is an internet protocol that sends information as a header on a
+            TCP connection without losing client data. When used with a NodeBalancer, it
+            enables the termination of TCP connections.
+
+
+            Linode NodeBalancers supports two versions, `v1` and `v2`. `v1` is human readable
+            text while `v2` makes use of a binary signature.
+
+
+            If ommited from the configuration, the default is `none`.
