+#### Volume Mapping

+You can map the "backgrounds" and "sites" directories as shown in the Docker Compose example above. After configuring volumes, the directories mapped on your host will be populated with Jump's default files when the container is next started. If the local directories contain files then they will persist going forward.

 ## Configuration
 
+### Open Weather Map
+
+You can configure Jump to get local time and weather updates by adding an Open Weather Map API key to `config.php` or passing the `OWPAPIKEY ` environment variable to the docker container (as described above).
+
+You will also need to provide a default `LATLONG` string, Jump will use this (e.g. "51.509865,-0.118092") until you press the location button and allow permission to get your location via the web browser.
