-The totem section contains three values.  All three values must be set
-or the corosync executive wll exit with an error.
-
-bindnetaddr specifies the address which the corosync Executive should bind to.
-This address should always end in zero.  If the local interface taffic
-should routed over is 192.168.5.92, set bindnetaddr to 192.168.5.0.
-
-mcastaddr is a multicast address.  The default should work but you may have
-a different network configuration.  Avoid 224.x.x.x because this is a "config"
-multicast address.
-
-mcastport specifies the UDP port number.  It is possible to use the same
-multicast address on a network with the corosync services configured for
-different UDP ports.
-
-The timeout section contains seven values.  This section is not normally used,
-but rather used to override the program defaults for the purposes of fine
-tuning for a given networking/processor combination or for debugging purposes.
-Be careful to use the same timeout values on each of the nodes in the cluster
-or unpredictable results may occur.
+The configuration directory (usually /etc/corosync) contains an example
+configuration file (corosync.conf.example). Please copy it as corosync.conf
+and edit it as needed. At the very minimum, the nodelist section will have to be changed
+to list all cluster nodes. For more information about the configuration file
+please read the corosync.conf.5 manual page.
