Hey @future-gigabyte-33261 👋 Elemental is made up of a software stack, which includes a Kubernetes Operator working with Rancher cluster only (a Rancher App). The Elemental Toolkit is the project that deals with installing/upgrading OS images from container registry, but while it could be used alone to bake your own OS image and also upgrade it, we are using it as a piece in the whole Elemental stack.
