+[elemental-operator](https://github.com/rancher/elemental-operator) The Elemental operator is responsible for managing the Elemental versions and maintaining a machine inventory to assist with edge or baremetal installations.
+
+This chart bootstraps an elemental-operator deployment on the [Rancher Manager v2.6](https://rancher.com/docs/rancher/v2.6/) cluster using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+
