-Starting with the v4.1.1 release your Pi-hole container may encounter issues starting the DNS service unless ran with the following setting:
-
-- `--dns=127.0.0.1 --dns=1.1.1.1` The second server can be any DNS IP of your choosing, but the **first dns must be 127.0.0.1**
-    - A WARNING stating "Misconfigured DNS in /etc/resolv.conf" may show in docker logs without this.
-- 4.1 required --cap-add NET_ADMIN until 4.2.1-1

-These are the raw [docker run cli](https://docs.docker.com/engine/reference/commandline/cli/) versions of the commands.  We provide no official support for docker GUIs but the community forums may be able to help if you do not see a place for these settings.  Remember, always consult your manual too!
+If the container wont start due to issues setting capabilities, set `DNSMASQ_USER` to `root` in your environment.
 
 ## Overview
 
-#### Renamed from `diginc/pi-hole` to `pihole/pihole`
-
 A [Docker](https://www.docker.com/what-docker) project to make a lightweight x86 and ARM container with [Pi-hole](https://pi-hole.net) functionality.
 
 1) Install docker for your [x86-64 system](https://www.docker.com/community-edition) or [ARMv7 system](https://www.raspberrypi.org/blog/docker-comes-to-raspberry-pi/) using those links. [Docker-compose](https://docs.docker.com/compose/install/) is also recommended.

 If you're using a Red Hat based distribution with an SELinux Enforcing policy add `:z` to line with volumes like so:
 
 ```
-    -v "$(pwd)/etc-pihole/:/etc/pihole/:z" \

 ```
 
 Volumes are recommended for persisting data across container re-creations for updating images.  The IP lookup variables may not work for everyone, please review their values and hard code IP and IPv6 if necessary.
 
 You can customize where to store persistent data by setting the `PIHOLE_BASE` environment variable when invoking `docker_run.sh` (e.g. `PIHOLE_BASE=/opt/pihole-storage ./docker_run.sh`).  If `PIHOLE_BASE` is not set, files are stored in your current directory when you invoke the script.
 
-Port 443 is to provide a sinkhole for ads that use SSL.  If only port 80 is used, then blocked HTTPS queries will fail to connect to port 443 and may cause long loading times.  Rejecting 443 on your firewall can also serve this same purpose.  Ubuntu firewall example: `sudo ufw reject https`
-
 **Automatic Ad List Updates** - since the 3.0+ release, `cron` is baked into the container and will grab the newest versions of your lists and flush your logs.  **Set your TZ** environment variable to make sure the midnight log rotation syncs up with your timezone's midnight.

-| Docker Environment Var. | Description |
-| ----------------------- | ----------- |
-| `ADMIN_EMAIL: <email address>`<br/> *Optional Default: ''* | Set an administrative contact address for the Block Page
-| `TZ: <Timezone>`<br/> **Recommended** *Default: UTC* | Set your [timezone](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) to make sure logs rotate at local midnight instead of at UTC midnight.
-| `WEBPASSWORD: <Admin password>`<br/> **Recommended** *Default: random* | http://pi.hole/admin password. Run `docker logs pihole \| grep random` to find your random pass.
-| `PIHOLE_DNS_: <IPs delimited by ;>`<br/> *Optional* *Default: 8.8.8.8;8.8.4.4* | Upstream DNS server(s) for Pi-hole to forward queries to, seperated by a semicolon <br/> (supports non-standard ports with `#[port number]`) e.g `127.0.0.1#5053;8.8.8.8;8.8.4.4`
-| `DNSSEC: <"true"\|"false">`<br/> *Optional* *Default: "false"* | Enable DNSSEC support
-| `DNS_BOGUS_PRIV: <"true"\|"false">`<br/> *Optional* *Default: "true"* | Enable forwarding of reverse lookups for private ranges
-| `DNS_FQDN_REQUIRED: <"true"\|"false">`<br/> *Optional* *Default: true* | Never forward non-FQDNs
-| `REV_SERVER: <"true"\|"false">`<br/> *Optional* *Default: "false"* | Enable DNS conditional forwarding for device name resolution
-| `REV_SERVER_DOMAIN: <Network Domain>`<br/> *Optional* | If conditional forwarding is enabled, set the domain of the local network router
-| `REV_SERVER_TARGET: <Router's IP>`<br/> *Optional* | If conditional forwarding is enabled, set the IP of the local network router
-| `REV_SERVER_CIDR: <Reverse DNS>`<br/> *Optional* | If conditional forwarding is enabled, set the reverse DNS zone (e.g. `192.168.0.0/24`)
-| `ServerIP: <Host's IP>`<br/> **Recommended** | **--net=host mode requires** Set to your server's LAN IP, used by web block modes and lighttpd bind address
-| `ServerIPv6: <Host's IPv6>`<br/> *Required if using IPv6* | **If you have a v6 network** set to your server's LAN IPv6 to block IPv6 ads fully
-| `VIRTUAL_HOST: <Custom Hostname>`<br/> *Optional* *Default: $ServerIP*   | What your web server 'virtual host' is, accessing admin through this Hostname/IP allows you to make changes to the whitelist / blacklists in addition to the default 'http://pi.hole/admin/' address
-| `IPv6: <"true"\|"false">`<br/> *Optional* *Default: "true"* | For unraid compatibility, strips out all the IPv6 configuration from DNS/Web services when false.
-| `INTERFACE: <NIC>`<br/> *Advanced/Optional* | The default works fine with our basic example docker run commands.  If you're trying to use DHCP with `--net host` mode then you may have to customize this or DNSMASQ_LISTENING.
-| `DNSMASQ_LISTENING: <local\|all\|NIC>`<br/> *Advanced/Optional* | `local` listens on all local subnets, `all` permits listening on internet origin subnets in addition to local.
-| `WEB_PORT: <PORT>`<br/> *Advanced/Optional* | **This will break the 'webpage blocked' functionality of Pi-hole** however it may help advanced setups like those running synology or `--net=host` docker argument.  This guide explains how to restore webpage blocked functionality using a linux router DNAT rule: [Alternative Synology installation method](https://discourse.pi-hole.net/t/alternative-synology-installation-method/5454?u=diginc)
-| `DNSMASQ_USER: <pihole\|root>`<br/> *Experimental Default: root* | Allows running FTLDNS as non-root.
-| `TEMPERATUREUNIT`: <c\|k\|f><br/>*Optional Default: c* | Set preferred temperature unit to `c`: Celsius, `k`: Kelvin, or `f` Fahrenheit units.
-| `WEBUIBOXEDLAYOUT: <boxed\|traditional>`<br/>*Optional Default: boxed* | Use boxed layout (helpful when working on large screens)
-| `SKIPGRAVITYONBOOT`: <Not Set\|1><br/> *Optional Default: Not Set* | Use this option to skip updating the Gravity Database when booting up the container.  By default this environment variable is not set so the Gravity Database will be updated when the container starts up.  Setting this environment variable to 1 (or anything) will cause the Gravity Database to not be updated when container starts up.
-| `QUERY_LOGGING: <"true"\|"false">`<br/> *Optional* *Default: "true"* | Enable query logging or not.

+| Variable | Default | Value | Description |
+| -------- | ------- | ----- | ---------- |
+| `INTERFACE` | unset | `<NIC>` | The default works fine with our basic example docker run commands.  If you're trying to use DHCP with `--net host` mode then you may have to customize this or DNSMASQ_LISTENING.
+| `DNSMASQ_LISTENING` | unset | `<local\|all\|single>` | `local` listens on all local subnets, `all` permits listening on internet origin subnets in addition to local, `single` listens only on the interface specified.
+| `WEB_PORT` | unset | `<PORT>` | **This will break the 'webpage blocked' functionality of Pi-hole** however it may help advanced setups like those running synology or `--net=host` docker argument.  This guide explains how to restore webpage blocked functionality using a linux router DNAT rule: [Alternative Synology installation method](https://discourse.pi-hole.net/t/alternative-synology-installation-method/5454?u=diginc)
+| `SKIPGRAVITYONBOOT` | unset | `<unset\|1>` | Use this option to skip updating the Gravity Database when booting up the container.  By default this environment variable is not set so the Gravity Database will be updated when the container starts up.  Setting this environment variable to 1 (or anything) will cause the Gravity Database to not be updated when container starts up.
+| `CORS_HOSTS` | unset | `<FQDNs delimited by ,>` | List of domains/subdomains on which CORS is allowed. Wildcards are not supported. Eg: `CORS_HOSTS: domain.com,home.domain.com,www.domain.com`.
+| `CUSTOM_CACHE_SIZE` | `10000` | Number | Set the cache size for dnsmasq. Useful for increasing the default cache size or to set it to 0. Note that when `DNSSEC` is "true", then this setting is ignored.
+| `FTLCONF_[SETTING]` | unset | As per documentation | Customize pihole-FTL.conf with settings described in the [FTLDNS Configuration page](https://docs.pi-hole.net/ftldns/configfile/). For example, to customize REPLY_ADDR6, ensure you have the `FTLCONF_REPLY_ADDR6` environment variable set.
+
+### Experimental Variables
+| Variable | Default | Value | Description |
+| -------- | ------- | ----- | ---------- |
+| `DNSMASQ_USER` | unset | `<pihole\|root>` | Allows changing the user that FTLDNS runs as. Default: `pihole`
+| PIHOLE_UID | debian system value | Number | Overrides image's default pihole user id to match a host user id  |
+| PIHOLE_GID | debian system value | Number | Overrides image's default pihole group id to match a host group id |
+| WEB_UID | debian system value | Number | Overrides image's default www-data user id to match a host user id |
+| WEB_GID | debian system value | Number | Overrides image's default www-data group id to match a host group id |
+| WEBLOGS_STDOUT | 0 | 0&vert;1 | 0 logs to defined files, 1 redirect access and error logs to stdout |

   * Ubuntu users see below for more detailed information
-* Port 80 is highly recommended because if you have another site/service using port 80 by default then the ads may not transform into blank ads correctly.  To make sure docker-pi-hole plays nicely with an existing webserver you run you'll probably need a reverse proxy webserver config if you don't have one already.  Pi-hole must be the default web app on the proxy e.g. if you go to your host by IP instead of domain then Pi-hole is served out instead of any other sites hosted by the proxy. This is the '[default_server](http://nginx.org/en/docs/http/ngx_http_core_module.html#listen)' in nginx or ['_default_' virtual host](https://httpd.apache.org/docs/2.4/vhosts/examples.html#default) in Apache and is taken advantage of so any undefined ad domain can be directed to your webserver and get a 'blocked' response instead of ads.
-  * You can still map other ports to Pi-hole port 80 using docker's port forwarding like this `-p 8080:80`, but again the ads won't render properly.  Changing the inner port 80 shouldn't be required unless you run docker host networking mode.
-  * [Here is an example of running with jwilder/proxy](https://github.com/pi-hole/docker-pi-hole/blob/master/docker-compose-jwilder-proxy.yml) (an nginx auto-configuring docker reverse proxy for docker) on my port 80 with Pi-hole on another port.  Pi-hole needs to be `DEFAULT_HOST` env in jwilder/proxy and you need to set the matching `VIRTUAL_HOST` for the Pi-hole's container.  Please read jwilder/proxy readme for more info if you have trouble.
+* You can map other ports to Pi-hole port 80 using docker's port forwarding like this `-p 8080:80` if you are using the default blocking mode. If you are using the legacy IP blocking mode, you should not remap this port.
+  * [Here is an example of running with nginxproxy/nginx-proxy](https://github.com/pi-hole/docker-pi-hole/blob/master/docker-compose-nginx-proxy.yml) (an nginx auto-configuring docker reverse proxy for docker) on my port 80 with Pi-hole on another port.
