@yubiuser , I found by accident this open PR. Can you please review and merge if you're happy with my addition? Thank you.

One day we might get: pi-hole/docker-pi-hole#1105

So should I close my PR as PADD will be fully integrated with Pi-hole?
Or are some lines in README regarding how to execute padd.sh still missing? 😉

[yubiuser]

No, it's fine this PR is still in draft mode. Just remember to adjust the README once it's merged.
