 ## Installation verification
 
 **Congratulations!** Your Reconmap instance should be up and running. To verify everything is working open your browser and head to http://localhost:5500 (unless host, IP are different) and enter the [default credentials](/admin-manual/default-credentials.html). You should see a Reconmap's dashboard. If something does not work, visit the [troubleshooting](/development/troubleshooting) page.
