+By default `weschleuder3` listens on port `3000` (you can change this by setting `$WEBSCHLOCKER_BIND_PORT` docker envvar) and will inform you about the IP address it is running on in the output.
 
 Once you have that, navigate your browser to `http://<IP-of-the-container>:3000/` and log-in with user `root@localhost`, password `slingit!`.
