+            Welcome to the new SondeHub Tracker v2!
+            <br/>
+            This version of the tracker uses data from the <a href="https://github.com/projecthorus/sondehub-infra/wiki">SondeHub v2</a> database, which will remove the excessive load that radiosondes 
+            have been placing on the Habitat tracking database. We are still working to being this tracker up to feature-parity with the previous
+            tracker, so some features like chase-cars and recovered sonde icons are still in-progress.
+            <br/>
+            Please be patient as we work to build up the feature set!
