+# Windows Helm Example
+
+This example will deploy the [Windows application example](https://kubernetes.io/docs/setup/production-environment/windows/user-guide-windows-containers/) packaged as a Helm chart.
+This must be deployed in a multi-cluster configuration.
+
+## Preparing Your Downstream Cluster(s)
+
+Clusters (`clusters.fleet.cattle.io`) must have the `windows.version` label in order for the example to be deployed.
+You can determine the value for the `windows.version` label key based on the release version of your Windows node(s).
+
+Description | Example
+--- | ---
+For Windows Server SAC nodes, the value will be the SAC release number prepended with "win". | 2004 SAC would result in `windows.version: win2004`
+For Windows Server LTSC nodes, the value will be the SAC release number that the LTSC is based on. | 2019 LTSC would result in `windows.version: win1809`
+
+## Creating the GitRepo
+
+Create the following `GitRepo` in your local cluster to get started.
+
+```yaml
+kind: GitRepo
+apiVersion: fleet.cattle.io/v1alpha1
+metadata:
+  name: helm
+  namespace: fleet-default
