+This is a cronjob schedule related image, which is very time sensitive. So it is very important to get the your time settings right. Luckily this image supports the `TZ` environment var for setting the timezone, so no worries. Just make sure to get it right like in the example below.
+
+The container exposes port `80` for using the web interface and the API, just forward that port to a port on your host. The web interface is located at `http://your.hostname:port/`. The API docs are below.

 ```sh
-$   docker run \
