+# UOS Linux
+
+UOS Linux(UnionTech OS Server 20) is supported with docker and containerd runtimes.
+
+**Note:** that UOS Linux is not currently covered in kubespray CI and
+support for it is currently considered experimental.
+
+There are no special considerations for using UOS Linux as the target OS
+for Kubespray deployments.
