 Proton VPN + qBtittorrent
 
 # How to use this image
+First you need to obtain the wireguard configurations from https://account.protonvpn.com/downloads: 
+- Enable VPN Accelerator
+- Enable NAT-PMP (Port Forwarding)
+- Select a server that supports p2p.
+
+Place this configuration file inside <localDir>/wireguard/
+
+Start the container using (or equivalent)  
+
+    docker run -d --privileged -v <localDir>:/config -p 8080:8080 ghcr.io/bubuntux/protorrent
+
+The container is gonna be accessible only locally or through the docker network, meaning that you will need a reverse proxy like [swag](https://github.com/linuxserver/docker-swag) or [traeffik](https://doc.traefik.io/traefik/providers/docker/) to access it when not running locally.
+
+You can also add an environment variable that would open the traffic to the specified network
+
+    docker run -d --privileged -v <localDir>:/config -p 8080:8080 -e NET_LOCAL=192.168.0.0/24 ghcr.io/bubuntux/protorrent
+
