+The CNCF and its parent the Linux Foundation take a vendor-neutral approach
+towards compatibility. It is possible to join your [Windows server](https://www.microsoft.com/en-us/windows-server)
+as a worker node to a Kubernetes cluster.
+
+You can [install and set up kubectl on Windows](/docs/tasks/tools/install-kubectl-windows/)
+no matter what operating system you use within your cluster.
+
+If you are using Windows nodes, you can read:
