+## Quickstart and documentation
+
+You can run Linkerd on any Kubernetes cluster in a matter of seconds. See the
+[Linkerd Getting Started Guide][getting-started] for how.
+
+For more comprehensive documentation, start with the [Linkerd
+docs][linkerd-docs].
+
+## Prerequisite: Linkerd Core Control-Plane

+to be installed first by following the [Linkerd Install
+Guide](https://linkerd.io/2/tasks/install/).
+
+## Adding Linkerd's Helm repository
+
+```bash
+# To add the repo for Linkerd edge releases:
+helm repo add linkerd https://helm.linkerd.io/edge
+```
+
+## Installing the Multicluster Controller Chart
+
+Note: Install the full `linkerd-multicluster` chart first.
+
+```bash
+helm install linkerd-multicluster-controller -n linkerd-multicluster
+```
+
+## Get involved
+
+* Check out Linkerd's source code at [GitHub][linkerd2].
+* Join Linkerd's [user mailing list][linkerd-users], [developer mailing
+  list][linkerd-dev], and [announcements mailing list][linkerd-announce].
