 ##<a name="k8s"></a>Installing Scope on Kubernetes
 
-To install Scope onto a Kubernetes cluster in Standalone Mode, follow these instructions.
+### With Weave Cloud (recommended)
 
-**Before You Begin**
+Weave Cloud runs the Scope UI for you, so you don't have to configure exposing and securing it for your team.
 
-* Ensure that the cluster allows privileged pods - this is required by the Scope probes. By default, privileged pods are allowed from Kubernetes 1.1 and up. If you are running an earlier version or a non-default configuration, ensure that your API Server and all of your Kubelets are launched with the flag `--allow_privileged`.
+Register for a [Weave Cloud account](https://cloud.weave.works/) to get a service token and then replace `<token>` with your token below, running this either on the master or on a machine where `kubectl` is configured to authenticate to your Kubernetes cluster:
 
-* The version of [kubectl](http://kubernetes.io/docs/user-guide/kubectl-overview/) must match the cluster version that you are using.
+    $ kubectl apply -f 'https://cloud.weave.works/launch/k8s/weavescope.yaml?service-token=<token>'
 
-* The cluster must support [DaemonSets](https://github.com/kubernetes/kubernetes/blob/master/docs/design/daemon.md).  DaemonSets are necessary to ensure that each Kubernetes node can run a Scope Probe.
+**SECURITY NOTE: This allows control of your Kubernetes cluster from Weave Cloud, which is a hosted service.**
 
-To enable DaemonSets in an existing cluster, add the `--runtime-config=extensions/v1beta1/daemonsets=true` argument to the [apiserver](https://github.com/kubernetes/kubernetes/blob/master/docs/admin/kube-apiserver.md)'s configuration. This is normally found in the `/etc/kubernetes/manifest/kube-apiserver.manifest`file after a restart of [the apiserver and controller manager](https://github.com/kubernetes/kubernetes/issues/18656) has occurred.  If you are creating a new cluster, set `KUBE_ENABLE_DAEMONSETS=true` in your cluster configuration.
-
-> **Note:** Prior to Kubernetes version 1.2 DaemonSets would fail to schedule pods on unschedulable nodes (typically the master).  This will result in the probe not running on that node.  See [#1030](https://github.com/weaveworks/scope/issues/1030) for more information.  It is advised that you use Kubernetes version 1.2 or higher.

-**Install Scope on Your Cluster**
-
-You can run Scope natively in your Kubernetes cluster using `kubectl` with a launch URL as show below.
+### Without Weave Cloud (run the Scope UI yourself)
 
 The simplest way to get the latest release of Scope deployed onto a Kubernetes cluster is by running the following:
 
-    kubectl create -f 'https://cloud.weave.works/launch/k8s/weavescope.yaml' --validate=false
+    $ kubectl apply -f 'https://cloud.weave.works/launch/k8s/weavescope.yaml'
 
 This runs a recent Scope image from the Docker Hub and launches a probe onto every node as well as a single app. Once launched, Scope doesn’t require any other configuration and it also doesn’t depend on Weave Net.
