+
+{{% capture overview %}}
+
+There are multiple guides on running Kubernetes with [CoreOS](https://coreos.com/kubernetes/docs/latest/).

+{{% capture body %}}
+
+## Official CoreOS Guides
+
+These guides are maintained by CoreOS and deploy Kubernetes the "CoreOS Way" with full TLS, the DNS add-on, and more. These guides pass Kubernetes conformance testing and we encourage you to [test this yourself](https://coreos.com/kubernetes/docs/latest/conformance-tests.html).
+
+* [**AWS Multi-Node**](https://coreos.com/kubernetes/docs/latest/kubernetes-on-aws.html)
+
+    Guide and CLI tool for setting up a multi-node cluster on AWS.
+    CloudFormation is used to set up a master and multiple workers in auto-scaling groups.
+
+* [**Bare Metal Multi-Node**](https://coreos.com/kubernetes/docs/latest/kubernetes-on-baremetal.html#automated-provisioning)
+
+    Guide and HTTP/API service for PXE booting and provisioning a multi-node cluster on bare metal.
+    [Ignition](https://coreos.com/ignition/docs/latest/) is used to provision a master and multiple workers on the first boot from disk.
+
+* [**Vagrant Multi-Node**](https://coreos.com/kubernetes/docs/latest/kubernetes-on-vagrant.html)
+
+    Guide to setting up a multi-node cluster on Vagrant.
+    The deployer can independently configure the number of etcd nodes, master nodes, and worker nodes to bring up a fully HA control plane.
+
+* [**Vagrant Single-Node**](https://coreos.com/kubernetes/docs/latest/kubernetes-on-vagrant-single.html)
+
+    The quickest way to set up a Kubernetes development environment locally.
+    As easy as `git clone`, `vagrant up` and configuring `kubectl`.
+
+* [**Full Step by Step Guide**](https://coreos.com/kubernetes/docs/latest/getting-started.html)
+
+    A generic guide to setting up an HA cluster on any cloud or bare metal, with full TLS.
+    Repeat the master or worker steps to configure more machines of that role.
+
+## Community Guides
+
+These guides are maintained by community members, cover specific platforms and use cases, and experiment with different ways of configuring Kubernetes on CoreOS.
+
