+### Docker container
+
+To use wetty as a docker container, a docker image is available on
+[docker hub](https://hub.docker.com/r/wettyoss/wetty). To run this image, use
+
+```sh
+docker run --rm -p 3000:3000 wettyoss/wetty --ssh-host=<YOUR-IP>
+```
+
+and you will be able to open a ssh session to the host given by `YOUR-IP` under
+the URL [http://localhost:3000/wetty](http://localhost:3000/wetty).
+
+It is recommended to drive wetty behind a reverse proxy to have HTTPS security
+and possibly Let’s Encrypt support. Popular containers to achieve this are
+[nginx-proxy](https://github.com/nginx-proxy/nginx-proxy) and
+[traefik](https://traefik.io/traefik/). For traefik there is an example
+docker-compose file in the containers directory.
