 A [Docker](https://www.docker.com/what-docker) project to make lightweight x86 and ARM continer with [pi-hole](https://pi-hole.net) functionality.  Why?  Maybe you don't have a Raspberry Pi lying around but you do have a Docker server.

 ## Docker tags
 
+The primary docker tags / versions are as follows.  [Click here to see the full list of tags](https://hub.docker.com/r/diginc/pi-hole/tags/), I also try to tag with the specific version of Pi-Hole Core / Web for historical or version pinning purposes.

 Any configuration files you volume mount into `/etc/dnsmasq.d/` will be loaded by dnsmasq when the container starts or restarts or if you need to modify the pi-hole config it is located at `/etc/dnsmasq.d/01-pihole.conf`.  The docker start scripts runs a config test prior to starting so it should tell you about any errors in the docker log.
 
 Similarly for the webserver you can customize configs in /etc/nginx (*:alpine* tag) and /etc/lighttpd (*:debian* tag).
