-*If you do not have your own web server, you can [create one](Web-server-links) in about five minutes for free.
+The application is now browsable at its ip address and port 80.
 
-Instructions for Docker setups are at [Docker Installation](Docker)
+You might want to add a `server_name` to the nginx config and remove
+it as a default server.
