+Background Data Updates
+---
+
+db-infoscreen can use <https://lib.finalrewind.org/dbdb/db_zugbildung_v0.json>
+to show scheduled ICE/IC types (ICE 1/2/3/4/T, IC 1/2), wagon orders, and other
+attributes. It expects the file to be provided in `share/zugbildungsplan.json`.
+
+As this information is updated regularly, the file is not shipped as part of
+this db-infoscreen distribution. It is recommended to retrieve it a few minutes
+after midnight via a daily cronjob. See `examples/dbf_update_zugbildungsplan`
+for a shell script.
+
+DBF will periodically reload `share/zugbildungsplan.json`. You can use your
+service supervisor (e.g. `systemctl reload db-infoscreen`) to force an
+immediate reload. You may also ignore the file entirely; it is entirely
+optional.
