+Tomcat supports installation of multiple instances. You can have a single installation of tomcat with multiple instances running on different IP/Port combinations, or multiple tomcat versions, each running 1 or more instances on different IP/Ports.
+</p>
+<p>
+Each Instance folder will need the following structure
+</p>
+<ul>
+<li>conf</li>
+<li>logs</li>
+<li>temp</li>
+<li>webapps</li>
+</ul>
+<p>
+At a minimum, conf should contain a copy of the following files from CATALINA_HOME\conf\server.xml. Any files not copied and edited, will be picked up by default from CATALINA_HOME\conf, i.e. CATALINA_BASE\conf files override defaults from CATALINA_HOME\conf.
+</p>
+<ul>
+<li>server.xml</li>
+<li>web.xml</li>
+</ul>
+<p>
+You must edit CATALINA_BASE\conf\server.xml to specify a unique IP/port for the instance to listen on. Find the line that contains <pre>&lt;Connector port="8080"</pre> and update the port number so as to specify a unique port
+</p>
+<p>
+To install an instance, first set the CATALINA_HOME environment variable to the name of the tomcat directory. Then create a second environment variable CATALINA_BASE and point this to the instance folder. Then run "service install" command specifying a service name
+</p>
+<p>
+<source>
+set CATALINA_HOME=c:\tomcat_7
+set CATALINA_BASE=c:\tomcat_7\instances\instance1
+service install instance1
+</source>
+</p>
+<p>
+To modify the service settings, you can run <b>tomcat7w //ES//instance1</b>
+</p>
+<p>
+For additional instances, create additional instance folder, update the CATALINA_BASE environment variable, and run the service install again
+</p>
+<p>
+<source>
+set CATALINA_BASE=c:\tomcat_7\instances\instance2
+service install instance2
