+# Hypershift POC
+
+All the following assumes `KUBECONFIG` points to the management cluster.
+
+Build binaries and push an image for the control plane operator:
+
+```
+$ make
+$ docker build -t quay.io/my/hypershift:latest .
+$ docker push quay.io/my/hypershift .
+```
+
+Install the operator's supporting resources into the management cluster:
+```
+$ oc apply --filename manifests/
+```
+
+Define release image info to be referenced by clusters:
+
+```
+hack/generate-release-images.rb | oc apply --filename -
+```
+
+Run the operator:
+```
+$ bin/hypershift-operator run --control-plane-operator-image quay.io/my/hypershift:latest
+```
+
+Create a cluster, referencing a release image present in the `release-images` configmap
+previously created:
+
+```yaml
+apiVersion: hypershift.openshift.io/v1alpha1
+kind: OpenShiftCluster
+metadata:
+  namespace: hypershift
+  name: guest-hello
+spec:
+  releaseImage: quay.io/openshift-release-dev/ocp-release@sha256:d78292e9730dd387ff6198197c8b0598da340be7678e8e1e4810b557a926c2b9
+  baseDomain: guest-hello.devcluster.openshift.com
+  pullSecret: '{"auths": { ... }}'
+  serviceCIDR: 172.30.0.0/16
+  podCIDR: 10.128.0.0/14
+  sshKey: 'ssh-rsa ...'
+  cloudProvider: AWS
+  computeReplicas: 1
+```
+
+Get the cluster kubeconfig using:
+```
+$ oc get secret --namespace guest-hello admin-kubeconfig --template={{.data.kubeconfig}} | base64 -D
+```
+
+And delete the cluster using:
+
+```
+$ oc delete --namespace hypershift openshiftclusters/guest-hello
+```
