 * piholeIP environment variable is required or default pi-hole scripts autodetect and give ads the private docker ip address that is not on your network so won't work.
  * A good way to test things are working right is by loading this page: [http://pi-hole.isworking.ok/admin/](http://pi-hole.isworking.ok/admin/)
- * I'm running jwilder/proxy on my port 80 already so I have `DEFAULT_HOST=pihole.mydomain.lan` (and matching VIRTUAL_HOST envs on the pihole) to ensure all the ad domains get served blank pages from my pihole container by default.
+ * [Here is an example of running with jwilder/proxy](https://github.com/diginc/docker-pi-hole/blob/master/jwilder-proxy-example-doco.yml) (an nginx auto-configuring docker reverse proxy for docker) on my port 80 with pihole on another porg.  Pi-hole needs to be `DEFAULT_HOST` env in jwilder/proxy and you need to set the matching `VIRTUAL_HOST` for the pihole.  Please read jwilder/proxy readme for more info if you have trouble.  I tested this basic exmaple which is based off what I run.
  * If you have something else taking up port 80 then the ads may not transform into blank ads correctly.  The solution to this is to make sure whatever you do have as the 'default' port 80 virtual host is redirect to this container.  
 * dnsmasq requires NET_ADMIN capabilities to run correctly in docker.
