+:::warning User namespaces required
+OpenChoreo's default build workflows run Argo Workflow pods that opt in to Kubernetes [user namespaces](https://kubernetes.io/docs/concepts/workloads/pods/user-namespaces/) by setting `hostUsers: false`. Use **Kubernetes 1.33 or newer**; Kubernetes 1.33 enables user namespaces by default when the node stack supports them.
+
+Every Linux node that can run Workflow Plane build pods must also provide:
+
+- **Linux kernel 6.3 or newer**
+- **containerd 2.0 or newer** or **CRI-O 1.25 or newer**
+- **runc 1.2 or newer** or **crun 1.9 or newer**
+
+See the [Kubernetes user namespaces guide](https://kubernetes.io/docs/concepts/workloads/pods/user-namespaces/) for details.
