In this documentation, an area is a named physical space. Areas are arranged hierarchically: the Duplex contains units, units contain rooms, and so on. Every device has a physical location, and that location is expressed as membership in an area using the isIn front matter property.

The full area hierarchy is documented under Areas. The two top-level areas are Unit A (Jean’s unit) and [Unit B](20-Areas/Duplex/Unit B/index.md) (Tim and Renee’s unit), both within the Duplex.
