# What is a Directory?
The Directory is a common location for all Devices and Groups. It is a root level that supports nesting. Parent groups are the first level of groups that are created within the Directory. This is where the devices can be associated with a Blueprint and manipulated remotely. Subgroups can be created inside Parent Groups. Groups can nest up to 5 levels deep and can host an unlimited number of devices at each level.
