Install a mongodb instance locally or on the host of your choice.
If your mongodb instance doesn't use default configuration values (anything different from localhost:27017 and no usr/pwd), you'll want to edit the file rtm.properties to set your custom values prior to moving to Step 2.
To start RTM, use either jetty via the following command line, simply using the jar file or add the war file to the webapps folder of a tomcat installation.
The webapp should then accessible through the url http://localhost:8099/rtm
