 Use a reverse proxy on your host server, such as [Træfik](https://traefik.io/)
 or [nginx](https://docs.nginx.com/nginx/admin-guide/web-server/reverse-proxy/),
 with HTTPS, for instance using [Let’s Encrypt](https://letsencrypt.org/).

+### Example with [docker-compose](https://docs.docker.com/compose/)
+
+A `docker-compose.yml` file is given as an example, using PostgreSQL. In order to use it, you have to adapt:
+- In the `postgresql` service:
+	* the `volumes` section;
+	* the `POSTGRES_PASSWORD` in the `environment` section;
+- In the `freshrss` service:
+	* the `volumes` section;
+	* options under the `labels` section are specific to [Træfik](https://traefik.io/), a reverse proxy. If you are not using it, feel free to delete this section. If you are using it, adapt accordingly to your config, especially the `traefik.frontend.rule` option.
+
+You can then launch the stack (postgres + freshrss) with:
+```sh
+docker-compose up -d
+```
