+This application is being put into maintenance mode. Additional features may be implemented for Nautobot 1.x. The functionality for Nautobot is being moved to the [Device Onboarding](https://docs.nautobot.com/projects/device-onboarding/en/latest/) application for Nautobot 2.x. The last NetBox support was version 2.x.
