 # VirtualMachine Snapshot Scheduler
 The **VirtualMachine Snapshot Scheduler** is a Kubernetes operator designed to automate the lifecycle of KubeVirt `VirtualMachineSnapshot` resources. It creates snapshots at defined intervals using cron expressions and manages their retention.
+
 ## Features
 - **Cron-based Scheduling**: Automatically creates `VirtualMachineSnapshot` objects at specified intervals.
 - **Multiple VM Support**: Selects VirtualMachines to snapshot using a `LabelSelector`.
 - **Retention Management**: Automatically deletes old snapshots based on a maximum count or TTL (Time to Live).
 - **Disable Schedule**: Disable snapshot creation by setting `disabled: true` while maintaining existing snapshots.
 - **Leader Election**: Supports high availability with leader election.
+
 ## Usage
 To enable scheduled snapshots for your VirtualMachines, create a `VirtualMachineSnapshotSchedule` resource.

 ## Configuration
-The controller can be configured using command-line flags or environment variables:
-| Flag | Environment Variable | Default | Description |
-|------|----------------------|---------|-------------|
-| `--kubeconfig` | - | - | Path to a kubeconfig file. |
-| `--leader-elect` | - | `false` | Enable leader election. |
+The controller can be configured using command-line flags or through the Helm chart:
+
+### Command-line Flags
+| Flag | Default | Description |
+|------|---------|-------------|
+| `--kubeconfig` | - | Path to a kubeconfig file. |
+| `--leader-elect` | `false` | Enable leader election. |
+| `--enable-owner-references` | `false` | Enable owner references and finalizers for snapshots. |
+
+## Deployment
+
+### Helm Chart
+A Helm chart is provided in the `charts/vmsnapshot-scheduler` directory.
+
+```bash
+helm install vmsnapshot-scheduler ./charts/vmsnapshot-scheduler -n vmsnapshot-scheduler --create-namespace
+```
+
+Ensure you configure the `namespace` correctly in your values or via `--set`.
+
+Enable `enableOwnerReferences` if you want to use owner references and finalizers for snapshots.
+When `VirtualMachineSnapshotSchedule` objects are deleted, all the related `VirtualMachineSnapshot` objects will be deleted as well.
