+To uninstall Palette from your cluster, you need to uninstall Palette management plane and Cert Manager. Optionally, you
+may have installed Image Swap and Reach system, which also need to be uninstalled. This uninstall process applies to
+both connected and airgap instances of self-hosted Palette.
+
+:::warning
+
+This uninstallation process only applies to Palette instances installed using Helm charts. If you used the Palette CLI
+to install Palette, this process does not apply.
+
+:::
+
+## Prerequisite
+
+- An active self-hosted Palette instance.
+
+- Access to the Kubernetes cluster where Palette is deployed.
+
+- Permissions to perform delete actions on all relevant cluster resources.
+
+- [Helm](https://helm.sh/docs/intro/install/) is installed and available on your host machine.
+
+- [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl) is installed and available on your host machine.
+
+## Uninstall Palette
+
+1. Ensure you are using the appropriate context where Palette is deployed.
+
+   ```shell
+   kubectl config current-context
+   ```
+
+2. Issue the following command to start uninstalling the Palette management plane. This will only remove the resources
+   managed by Helm and the remaining resources will require additional manual intervention.
+
+   ```shell
+   helm uninstall hubble
+   ```
+
+3. Issue the following command to remove the namespace and custom resource definitions related to the Palette management
+   plane.
+
+   ```shell
+   kubectl delete namespace hubble-system || kubectl delete crd spectroclusteractions.jet.cluster.spectrocloud.com
+   ```
+
+4. Issue the following command to uninstall Cert Manager. Cert Manager does not reply on any Helm hooks and the Helm
+   uninstall command will uninstall all related resources.
+
+   ```shell
+   helm uninstall cert-manager
+   ```
+
+5. (Optional) If you installed Reach, issue the following command to start uninstalling Reach. This will remove all
+   resources related to Reach that are managed by Helm. However, some resources created by Helm hooks are not managed by
+   Helm and will require additional manual intervention to remove.
+
+   ```shell
+   helm uninstall reach-system
+   ```
+
+6. (Optional) Issue the following commands to remove the remaining Reach system resources.
+
+   ```shell
+   kubectl delete ns reach-system
+   kubectl delete crd podpresets.reach.spectrocloud.com clusterpodpresets.reach.spectrocloud.com
+   kubectl delete mutatingwebhookconfiguration reach-mutating-webhook-configuration
+   kubectl delete validatingwebhookconfiguration reach-validating-webhook-configuration
+   kubectl delete clusterrolebinding reach-manager-rolebinding
+   kubectl delete clusterrolebinding reach-proxy-rolebinding
+   kubectl delete clusterrole reach-manager-role
+   kubectl delete clusterrole reach-metrics-reader
+   kubectl delete clusterrole reach-proxy-role
+   ```
+
+7. (Optional) If you installed Image Swap, issue the following command to remove the `image-swap` chart.
+
+   ```shell
+   helm uninstall image-swap
+   ```
+
+8. (Optional) Issue the following commands to remove the remaining resources related to `image-swap`.
+
+   ```shell
+   kubectl delete ns imageswap-system
+   kubectl delete mutatingwebhookconfiguration imageswap-webhook
+   kubectl delete csr imageswap.imageswap-system.cert-request
+   ```
+
+## Validate
+
+1. Connect to your cluster via kubectl.
+
+2. Issue the following command to get a list of the remaining namespaces. Confirm that all Palette-related namespaces
+   have been deleted.
+
+   ```shell
+   kubectl get namespaces
+   ```
+
+3. Issue the following command to confirm that all charts have been uninstalled.
+
+   ```shell
+   helm ls
+   ```
+
+4. Issue the following command to retrieve all resources in your cluster across all namespaces. Confirm that no
+   Palette-related resources are remaining.
+
+   ```shell
+   kubectl get all --all-namespaces
+   ```
