+Watchtower is itself packaged as a Docker container so installation is as simple as pulling the `v2tec/watchtower` image. If you are using ARM based architecture, pull the appropriate `v2tec/watchtower:armhf-<tag>` image from the [v2tec Docker Hub](https://hub.docker.com/r/v2tec/watchtower/tags/). 
 
 Since the watchtower code needs to interact with the Docker API in order to monitor the running containers, you need to mount */var/run/docker.sock* into the container with the -v flag when you run it.
