 .SH DESCRIPTION
 \fBdisorder-playrtp\fR plays a network broadcast sent from the specified
 address.
 .PP
-Normally the \fIADDRESS\fR would be 0.0.0.0.  The \fIPORT\fR will depend on the
-server configuration.  You may need to specify the \fB--multicast\fR option
-(see below) and if you have more than one soundcard perhaps the \fB--device\fR
-option.
+If neither a group nor port are specified then the local DisOrder
+configuration is consulted to find the server and the server is asked where the
+RTP stream is.
+.PP
+If just a port is specified then the RTP stream is assumed to be unicast or
+broadcast to that port.
+.PP
+If a group and a port are specified then the RTP stream is assumed to be
+multicast to that group and port.
 .SH OPTIONS

-Specifies a multicast group to join.  This is necessary if the network
-broadcast is being multicasted rather than broadcast.
