+  - For custom Wireguard configurations using [the custom provider](https://github.com/qdm12/gluetun/wiki/Custom-provider)
+  - More in progress, see [#134](https://github.com/qdm12/gluetun/issues/134)
 - DNS over TLS baked in with service provider(s) of your choice
 - DNS fine blocking of malicious/ads/surveillance hostnames and IP addresses, with live update every 24 hours
 - Choose the vpn network protocol, `udp` or `tcp`
 - Built in firewall kill switch to allow traffic only with needed the VPN servers and LAN devices
 - Built in Shadowsocks proxy (protocol based on SOCKS5 with an encryption layer, tunnels TCP+UDP)
 - Built in HTTP proxy (tunnels HTTP and HTTPS through TCP)

 - Compatible with amd64, i686 (32 bit), **ARM** 64 bit, ARM 32 bit v6 and v7, and even ppc64le 🎆
-- VPN server side port forwarding for Private Internet Access and Vyprvpn
+- [Custom VPN server side port forwarding for Private Internet Access](https://github.com/qdm12/gluetun/wiki/Private-internet-access#vpn-server-port-forwarding)
 - Possibility of split horizon DNS by selecting multiple DNS over TLS providers
-- Subprograms all drop root privileges once launched
+- Unbound subprogram drops root privileges once launched
-- Subprograms output streams are all merged together
 - Can work as a Kubernetes sidecar container, thanks @rorph
 
 ## Setup
 
-1. On some devices you may need to setup your tunnel kernel module on your host with `insmod /lib/modules/tun.ko` or `modprobe tun`
+🎉 There are now instructions specific to each VPN provider with examples to help you get started as quickly as possible!
-    - [Synology users Wiki page](https://github.com/qdm12/gluetun/wiki/Synology-setup)
-1. ⚠️ Raspberry Pi users running 32 bit systems: from image `v3.16.0` you need to do [this](https://github.com/alpinelinux/docker-alpine/issues/135#issuecomment-812287338) on your host to run the container.
-1. Launch the container with:
 
-    ```bash
+Go to the [Wiki](https://github.com/qdm12/gluetun/wiki)!
-    docker run -d --name gluetun --cap-add=NET_ADMIN \
+
-    -e VPNSP="private internet access" -e REGION="CA Montreal" \
+[🐛 Found a bug in the Wiki?!](https://github.com/qdm12/gluetun/issues/new?assignees=&labels=%F0%9F%93%84+Wiki+issue&template=wiki+issue.yml&title=Wiki+issue%3A+)
-    -e OPENVPN_USER=js89ds7 -e OPENVPN_PASSWORD=8fd9s239G \
+
-    -v /yourpath:/gluetun \
+Here's a docker-compose.yml for the laziest:
-    qmcgaw/gluetun
+
+```yml
+version: "3"
+services:
+  gluetun:
+    image: qmcgaw/gluetun
+    cap_add:
+      - NET_ADMIN
+    ports:
+      - 8888:8888/tcp # HTTP proxy
+      - 8388:8388/tcp # Shadowsocks
+      - 8388:8388/udp # Shadowsocks
+    volumes:
+      - /yourpath:/gluetun
+    environment:
+      # See https://github.com/qdm12/gluetun/wiki
+      - VPNSP=ivpn
+      - VPN_TYPE=openvpn
+      # OpenVPN:
+      - OPENVPN_USER=
+      - OPENVPN_PASSWORD=
+      # Wireguard:
+      # - WIREGUARD_PRIVATE_KEY=wOEI9rqqbDwnN8/Bpp22sVz48T71vJ4fYmFWujulwUU=
+      # - WIREGUARD_ADDRESS=10.64.222.21/32
+      # Timezone for accurate log times
+      - TZ=
 ```
 
-    or use [docker-compose.yml](https://github.com/qdm12/gluetun/blob/master/docker-compose.yml) with:
-
-    ```bash
-    echo "your openvpn username" > openvpn_user
-    echo "your openvpn password" > openvpn_password
-    docker-compose up -d
-    ```
-
-    You should probably check the many [environment variables](https://github.com/qdm12/gluetun/wiki/Environment-variables) available to adapt the container to your needs.
-
-## Further setup
-
-The following points are all optional but should give you insights on all the possibilities with this container.
-
-- Use [Docker secrets](https://github.com/qdm12/gluetun/wiki/Docker-secrets) to read your credentials instead of environment variables
-- [Test your setup](https://github.com/qdm12/gluetun/wiki/Test-your-setup)
-- [How to connect other containers and devices to Gluetun](https://github.com/qdm12/gluetun/wiki/Connect-to-gluetun)
-- [VPN server side port forwarding](https://github.com/qdm12/gluetun/wiki/Port-forwarding)
-- [HTTP control server](https://github.com/qdm12/gluetun/wiki/HTTP-Control-server) to automate things, restart Openvpn etc.
-- Update the image with `docker pull qmcgaw/gluetun:latest`. See this [Wiki document](https://github.com/qdm12/gluetun/wiki/Docker-image-tags) for Docker tags available.
