 ## Use Docker to run [Pi-Hole](https://pi-hole.net) with an upstream [Unbound](https://nlnetlabs.nl/projects/unbound/about/) resolver.
 
-This repo has a different `docker-compose` config in the folder-- choose your favorite. The `two-container` config may work better on Synology due to usage of `macvlan` networking which helps prevent port conflicts with the host.
-
 - [`one-container`](one-container/) (new) - Install Unbound directly into the Pi-Hole container
   - This configuration contacts the DNS root servers directly, please read the Pi-Hole docs on [Pi-hole as All-Around DNS Solution](https://docs.pi-hole.net/guides/unbound/) to understand what this means.
   - With this approach, we can also simplify our Docker networking since `macvlan` is no longer necessary.
