 ## About this Library
 
-This library is intended to be used for populating device types in [NetBox](https://github.com/netbox-community/netbox)
-version 2.7 or later. It contains a set of device type definitions expressed in YAML and arranged by manufacturer. Each
-file represents a discrete physical device type (e.g. make and model). These definitions can be loaded into NetBox to
-obviate the need to create device types and their associated components manually.

+- `u_height`: The height of the device type in rack units. Increments of 0.5U are supported. (Default: 1)
