 This page describes the software, hardware, and networking requirements for the nodes where the Rancher server will be installed. The Rancher server can be installed on a single node or a high-availability Kubernetes cluster.
 
-> It is important to note that if you install Rancher on a Kubernetes cluster, requirements are different from the [node requirements for downstream user clusters,](../how-to-guides/new-user-guides/kubernetes-clusters-in-rancher-setup/node-requirements-for-rancher-managed-clusters.md) which will run your apps and services.
