+PeerTube needs a PostgreSQL and a Redis instance to work correctly. If you want
+to quickly set up a full environment, either for trying the service or in
+production, you can use a `docker-compose` setup.
+
+```bash
+$ cd /your/peertube/directory
+$ mkdir ./docker-volume && mkdir ./docker-volume/traefik
+$ curl "https://raw.githubusercontent.com/chocobozzz/PeerTube/master/support/docker/production/config/traefik.toml" > ./docker-volume/traefik/traefik.toml

+$ curl -s "https://raw.githubusercontent.com/chocobozzz/PeerTube/master/support/docker/production/docker-compose.yml" > ./docker-compose.yml
+```
+
+Update the reverse proxy configuration:
+
+```
+$ vim ./docker-volume/traefik/traefik.toml
+```
+
+Tweak the `docker-compose.yml` file there according to your needs:
+
+```
+$ vim ./docker-compose.yaml
+```
+
+You can use the regular `up` command to set it up, with possible overrides of
+the environment variables:
+
+```bash
+$ PEERTUBE_WEBSERVER_HOSTNAME="domain.tld" docker-compose up
+```
+
+Other environment variables are used in
+`support/docker/production/config/custom-environment-variables.yaml` and can be
+intuited from usage.
