 ## Verifying kubectl configuration
 
-In order for kubectl to find and access a Kubernetes cluster, it needs a [kubeconfig file](/docs/tasks/access-application-cluster/configure-access-multiple-clusters/), which is created automatically when you create a cluster using kube-up.sh or successfully deploy a Minikube cluster. See the [getting started guides](/docs/setup/) for more about creating clusters. If you need access to a cluster you didn't create, see the [Sharing Cluster Access document](/docs/tasks/access-application-cluster/configure-access-multiple-clusters/).
