 The container is available from the Docker registry and this is the simplest way to get it. To run the container use this command:
 
 ```
-docker run --privileged  -d -v /your/storage/path/:/data -v /your/config/path/:/config -p 9091:9091 haugene/transmission-openvpn
+$ docker run --privileged  -d -v /your/storage/path/:/data -v /your/config/path/:/config -p 9091:9091 haugene/transmission-openvpn
 ```
 
 As you can see, the container expects two volumes to be mounted. One is used for storing your downloads from Transmission, and the other provides configurations. The container comes with a default Transmission settings.json file that expects the folders "completed, incomplete and watch" to be present in /your/storage/path (aka /data). This is where Transmission will store your downloads, incomplete downloads and a watch directory to look for new .torrent files.

 There are several ways to fix this. You can pipe and do fancy iptables or ip route configurations on the host and in the Docker image. But I found that the simplest solution is just to proxy my traffic. Start a Nginx container like this:

 ### What if I want to run the container interactively.
-If you want do have access inside the container while running, do like this.
+If you want do have access inside the container while running you have two choices. To have a look inside an already running container, use docker exec to get a terminal inside the container.
 
 ```
-docker run --privileged -v /mnt/disk1/Torrents/:/data -v /your/config/path/:/config -p 9091:9091 -it --entrypoint=/bin/bash docker-transmission-openvpn

 ```
 
-This will start the container and give you a bash shell to work from. The container has screen installed, so you can use screen to start the init system which starts openVPN and Transmission. Then you can detach from screen and continue to use bash inside the running container. If you're unfamiliar with screen, read up on it. The commands are as follows:
+If you want to start the container without it starting OpenVPN on boot, then run the image without daemonizing and use bash as entrypoint.

-You should now be detached and both services should be running.
