+# Leader Worker Set Operator
+
+Install Leader Worker Set Operator.
+
+Do not use the `base` directory directly, as you will need to patch the `channel` based on the version of OpenShift you are using, or the version of the operator you want to use.
+
+The current *overlays* available are for the following channels:
+
+* [stable-v1.0](operator/overlays/stable-v1.0)
+* [v1.10](operator/overlays/v1.10)
+* [v1.11](operator/overlays/v1.11)
+* [v22.9](operator/overlays/v22.9)
+* [v23.3](operator/overlays/v23.3)
+
+## Usage
+
+If you have cloned the `gitops-catalog` repository, you can install NVIDIA GPU Operator based on the overlay of your choice by running from the root (`gitops-catalog`) directory.
+
+```
+oc apply -k leader-worker-set/operator/overlays/<channel>
+```
+
+Or, without cloning:
+
+```
+oc apply -k https://github.com/redhat-cop/gitops-catalog/leader-worker-set/operator/overlays/<channel>
+```
+
+As part of a different overlay in your own GitOps repo:
+
+```
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+resources:
+  - https://github.com/redhat-cop/gitops-catalog/leader-worker-set/operator/overlays/<channel>?ref=main
+```
