 ## Build a cluster
 
 Before deploying OpenFaaS, you should provision a Kubernetes cluster. There are many options for deploying a local or remote cluster. You can read about the [various Kubernetes distributions here](https://kubernetes.io/docs/setup/).

 ### Local clusters
 
-* [k3s](https://k3s.io) - a light-weight Kubernetes distribution ideal for edge and development - compatible with Raspberry Pi & ARM64 (Equinix Metal, AWS Graviton, etc)
+Below are the most popular ways to run a local Kubernetes cluster, but OpenFaaS should run on any.

 * [k3d](https://github.com/rancher/k3d) - makes k3s available on any computer where Docker is also running
-* [microk8s](https://microk8s.io) - a Kubernetes distribution, specifically for Ubuntu users.
+* [KinD](https://kind.sigs.k8s.io) - upstream Kubernetes running inside a Docker container.

 * [minikube](https://minikube.sigs.k8s.io) - a popular, but heavy-weight option that creates a Linux virtual machine your computer using VirtualBox or similar
-* [Docker for Mac/Windows](https://docs.docker.com/docker-for-mac/install/) - Docker's Desktop edition has an option to run a local Kubernetes cluster

 ### Remote/managed options
 
 You can run `k3s` and `k3d` on a single node Virtual Machine so that you don't have to run Kubernetes on your own computer.

 * `arkade install` - arkade installs OpenFaaS to Kubernetes using its official helm chart and is the easiest and quickest way to get up and running.
 
 * Helm chart - sane defaults and easy to configure through YAML or CLI flags. Secure options such as `helm template` or `helm 3` also exist for those working within restrictive environments.
