+## Running Pi-hole in a Docker Container
+If you're running Pi-hole in a Docker Container you can use `padd.sh` this way:
+### Simplest, but quick & dirty solution:
+Copy `padd.sh` to your `/etc/pihole` volume/mount on your linux host where docker is running. Then execute `docker exec pihole /etc/pihole/padd.sh` and voila!
+### Slightly more complicated, but very elegant solution:
+If you want `padd.sh` not mixed up with your config files add this line to your [docker_run.sh](https://github.com/pi-hole/docker-pi-hole/blob/master/docker_run.sh#L14) in your Pi-hole
+`-v "${PIHOLE_BASE}/opt-padd/:/opt/padd/"`
+or [docker-compose.yml](https://github.com/pi-hole/docker-pi-hole/blob/master/docker-compose.yml.example#L19):
+```
+volumes:
+- './opt-padd/:/opt/padd/'
+```
+Where `./opt-padd` is your local directory where `padd.sh` has been copied to (or your cloned git repo).
+Then execute `docker exec pihole /opt/padd/padd.sh` and voila!
