+description: A Helm chart for karmada-operator
+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+
+# The optional kubeVersion field can define semver constraints on supported Kubernetes versions.
+# Helm will validate the version constraints when installing the chart and fail if the cluster
+# runs an unsupported Kubernetes version.

+The Karmada operator is a method for installing, upgrading, and deleting Karmada instances. It builds upon the basic Karmada resource and controller concepts and provides convenience to centrally manage the entire lifecycle of Karmada instances in a global cluster. With the operator, you can extend Karmada with custom resources (CRs) to manage your instances not only in local clusters but also in remote clusters.
+
+This page provides instructions on how to install, upgrade, and uninstall Karmada-operator.
+
+## Prerequisites
+
+- Kubernetes 1.16+
+- helm v3+
+
+| Repository | Name | Version |
+|------------|------|---------|
+| https://charts.bitnami.com/bitnami | common | 1.x.x |
+
+## Installing or upgrading the Chart
+
+Go to the root directory of the `karmada-io/karmada` repo. To install or upgrade the Helm Chart with
+the release name `karmada-operator` in the `karmada-system` namespace.
+
+```bash
+helm upgrade --install karmada-operator --create-namespace ./charts/karmada-operator \
+--set operator.replicaCount=<replica_count> \
+--set operator.image.registry=<image_registry> \
+--set operator.image.repository=<image_repository> \
+--set operator.image.tag=<image_tag>
+-n karmada-system --version <chart_version>
+```
+
+For example, you can simply run the helm command:
+
+```bash
+helm install karmada-operator -n karmada-system --create-namespace --dependency-update ./charts/karmada-operator
+```
+
+Then, check the status of `karmada-operator` pod.
+
+```console
+kubectl get po -n karmada-system
+NAME                               READY   STATUS    RESTARTS   AGE
+karmada-operator-df95586f6-d5bll   1/1     Running   0          6s
+```
+
+## Uninstalling the Chart
+
+To uninstall/delete the `karmada-operator` helm release in the `karmada-system` namespace, run:
+
+```bash
+helm uninstall karmada-operator -n karmada-system
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
