                        <p>
                          Thank you for taking the time to download and install TSM Monitor.

                        <p>
                          TSM Monitor is a web application written in PHP to help TSM administrators
                          to quickly get reports and health status information of their TSM servers.
                          It generates it's content dynamically so one can easily add or modify queries
                          to adapt the application to one's own needs. Before you can start using TSM
                          Monitor, there are a few configuration steps that need to be done.
                        </p>
                        <p>
                          Make sure you have read and followed the required steps needed to install
                          TSM Monitor before continuing. Install information can be found here

                          The default '<b>admin</b>' user has full rights to the TSM Monitor application, which
