 Your new `traefik` instance will detect that a new app is coming up and generate SSL certificates for it. You can see what `traefik` is up to using the same commands above but replacing `<netcloud-domain>` with the `<traefik-domain>` you chose earlier (`abra app ls` will remind you what domains you chose :grinning:).
 
-### Upgrade Nextcloud
-
-To upgrade an app manually to the newest available version run:
-
-```bash
-abra app upgrade <nextcloud-domain>

-### Automatic Upgrades
-
-`kadabra` the auto-updater is still under development, use it with care and don't use it in production environments.
-To setup the auto-updater copy the `kadabra` binary to the server and configure a cronjob for regular app upgrades.
-The following script will configure ssmtp for email notifications and setup a cronjob.
-This cronjob checks daily for new app versions, notifies if any kind of update is available and upgrades all apps to the latest patch/minor version.
-
-
-```bash
-apt install ssmtp
-
-cat > /etc/ssmtp/ssmtp.conf << EOF

 ## Finishing up
 
 Hopefully you got something running! Well done! The [operators handbook](/operators/handbook) would probably be the next place to go check out if you're looking for more help. Especially on topics of ongoing maintenance.
