+This Docker deployment runs both Pi-Hole and Unbound in a single container.
 
 The base image for the container is the [official Pi-Hole container](https://hub.docker.com/r/pihole/pihole), with an extra build step added to install the Unbound resolver directly into to the container based on [instructions provided directly by the Pi-Hole team](https://docs.pi-hole.net/guides/unbound/).
 
 ## Usage
