+To run the demo, first start the IceGrid service:
+
+$ icegridnode --Ice.Config=config --warn
+
+In a separate window:
+
+$ icegridadmin --Ice.Config=config -e "application add 'application.xml'"
+$ client
+
+This will deploy the servers described in the file "application.xml"
+and start the client.
+
+Messages will be displayed in the IceGrid service window.
+
+To remove the application:
+
+$ icegridadmin --Ice.Config=config -e "application remove Simple"
+
+You can also use the following descriptors to deploy the application:
+
+- application_with_templates.xml: This descriptor demonstrates the use
+  of templates for the server definition. Templates make it easy to
+  deploy multiple instances of the same server. To deploy a new server
+  based on the template, use the following command:
+  
+  $ icegridadmin --Ice.Config=config -e "server template instantiate \
+    Simple localhost SimpleServer index=2"
+
+  This will deploy a new server based on the `SimpleServer' template.
+
+- application_with_replication.xml: This descriptor demonstrates the
+  use of replication to balance the load of the application over
+  several servers.
