 .SH DESCRIPTION
 
 \fBmonkeysphere-ssh-proxy\fP is an ssh proxy command that can be used
-to trigger a monkeysphere update of the known_hosts file for the hosts
-that are being connected to.  It is meant to be run as an ssh
-ProxyCommand.  This can either be done by specifying the proxy command
-on the command line:
+to trigger a monkeysphere update of the ssh known_hosts file for a
+host that is being connected to with ssh.  This works by updating the
+known_hosts file for the host first, before an attempted connection to
+the host is made.  Once the known_hosts file has been updated, a TCP
+connection to the host is made by exec'ing netcat(1).  Regular ssh
+communication is then done over this netcat TCP connection (see
+ProxyCommand in ssh_config(5) for more info).
+
+This command is meant to be run as the ssh "ProxyCommand".  This can
+either be done by specifying the proxy command on the command line:
 
 .B ssh -o ProxyCommand="monkeysphere-ssh-proxycommand %h %p" ...

+This will run everything except the final exec of netcat to make the
