 * [Large clusters](#large-clusters): Ingress on GCE isn't supported on large (>1000 nodes), single-zone clusters.
 * [Teardown](README.md#deletion): The recommended way to tear down a cluster with active Ingresses is to either delete each Ingress, or hit the `/delete-all-and-quit` endpoint on GLBC, before invoking a cluster teardown script (eg: kube-down.sh). You will have to manually cleanup GCE resources through the [cloud console](https://cloud.google.com/compute/docs/console#access) or [gcloud CLI](https://cloud.google.com/compute/docs/gcloud-compute/) if you simply tear down the cluster with active Ingresses.
 * [Changing UIDs](#changing-the-cluster-uid): You can change the UID used as a suffix for all your GCE cloud resources, but this requires you to delete existing Ingresses first.
-* [Cleaning up](#cleaning-up-cloud-resources): You can delete loadbalancers that older clusters might've leaked due to permature teardown through the GCE console.
