Scheduled content updates using Launches

Use Case

Acme Corp is a gas station franchise that uses Screens for its gas prices billboards. Gas prices are updated once a week, on Monday mornings right after midnight, but the content is prepared the week before and validated before it gets pushed to the various locations. Moreover, the company does not want its authors to have to manually push the content over night to the Screens, so it uses a scheduled content update mechanism to roll out the changes.

This how-to project walks you through how to use the concept of Launches to achieve this.

The project has a simple sequence channel. A Launch has been prepared with some content modifications, but hasn't been rolled out yet (i.e. it is unpromoted. Authors can manually promote the Launch or schedule an automatic Launch Date if needed.
