       Alternatively you can use <code>telnet</code> instead
-      of <code>raw</code> TCP.  <span class="since">Since 0.8.5</span>
-      you can also use <code>telnets</code>
-      (secure telnet) and <code>tls</code>.
+      of <code>raw</code> TCP in order to utilize the telnet protocol
+      for the connection.

+      <span class="since">Since 0.8.5,</span> some hypervisors support
+      use of either <code>telnets</code> (secure telnet) or <code>tls</code>
+      (via secure sockets layer) as the transport protocol for connections.
