  * Where a bookable thing physically is: a room of the office, an area of the car park.
  *
  * A group belongs to exactly one ResourceType, because "Raum Nord" means nothing for parking.
- * It is a description of the building, so it is configuration seeded alongside the resources
- * rather than something a user creates.
+ * It is a description of the building, maintained by an administrator under /admin/resources.
  *
  * Note there is deliberately no method named `group`, `label` or `position` other than the plain
  * accessors: Twig resolves `x.label` to a method of that literal name before trying getLabel(),
