You can optionally uncomment the tor socks proxy in the docker-compose.yml. If so, you can make use of changedetection to watch and monitor .onion siteds in the darknet.

For this to work, you have to place the proxies.json file at the docker bind mount volume /mnt/docker-volumes/changedetection/config/proxies.json.

Then restart the container. Within changedetection, you can now choose the proxy to use.
