 # Docker guide
 
-## Test/Development 
-
-You can quickly get a server running using Docker. You need to have [docker](https://www.docker.com/community-edition) and [docker-compose](https://docs.docker.com/compose/install/) installed.
-
-For this example configuration, you should also run a reverse proxy. The example
-Docker Compose file provides example labels for the Traefik load balancer,
-though any HTTP reverse proxy is compatible.
-
-Example for running a PeerTube server locally:
-
-```bash
-$ wget https://github.com/chocobozzz/PeerTube/raw/develop/support/docker/production/docker-compose.yml
-$ sudo \
-    PEERTUBE_HOSTNAME=peertube.lvh.me \
-    PEERTUBE_ADMIN_EMAIL=test@example.com \
-    PEERTUBE_TRANSCODING_ENABLED=true \
-    docker-compose up app
-```
-
-(Get the initial root user password from the program output.)
+You can quickly get a server running using Docker. You need to have
+[docker](https://www.docker.com/community-edition) and
+[docker-compose](https://docs.docker.com/compose/install/) installed.
 
 ## Production
 
-PR welcome!
+### Build your own Docker image
+
+```bash
+$ git clone https://github.com/chocobozzz/PeerTube /tmp/peertube
+$ cd /tmp/peertube
+$ docker build . -f ./support/docker/production/Dockerfile.stretch
+```
+
+### Run a preconfigured setup with all dependencies
+
+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
+$ git clone https://github.com/chocobozzz/PeerTube /tmp/peertube
+$ cd /tmp/peertube/support/docker/production
+```
+
+Then tweak the `docker-compose.yml` file there according to your needs. Then
+you can use the regular `up` command to set it up, with possible overrides of
+the environment variables:
+
+```bash
+$ PEERTUBE_HOSTNAME=peertube.lvh.me \
+  PEERTUBE_ADMIN_EMAIL=test@example.com \
+  PEERTUBE_TRANSCODING_ENABLED=true \
+  PEERTUBE_SIGNUP_ENABLED=true \
+  PEERTUBE_SMTP_HOST=mail.lvh.me \
+  PEERTUBE_SMTP_PORT=1025 \
+  PEERTUBE_SMTP_FROM=noreply@peertube.lvh.me \
+    docker-compose up
+```
+
+Other environment variables are used in
+`support/docker/production/config/custom-environment-variables.yaml` and can be
+intuited from usage.
+
+For this example configuration, a reverse proxy is quite recommended. The
+example Docker Compose file provides example labels for a Traefik load
+balancer, although any HTTP reverse proxy will work fine. See the example
+Nginx configuration `support/nginx/peertube` file to get an idea of
+recommendations and requirements to run PeerTube the most efficiently.
+
+**Important**: note that you'll get the initial `root` user password from the
+program output, so check out your logs to find them.
+
+## Development
+
+The Docker image that's preconfigured in `support/docker/dev` contains all the
+services embedded in one image, so as to work correctly on
+[Janitor](https://janitor.technology). It is much not advised to use it in
+production.
