+
+Provision a kind cluster with access to a local docker repository:
+
+```bash
+./scripts/kind-with-registry.sh
+```
+
+Then follow the [instructions here](../../docs/kind-deployment.md), excluding the step already performed to provision the kind cluster.
+
+To generate and use Operator Lifecycle Manager components access to a docker repository is required, for local testing use:
+
+```bash
+export DOCKER_REPO="localhost:5000"
+```
+
+Generate and publish the gaffer helm operator artifacts using this script:
+
+```bash
+./scripts/generate-helm-operator.sh "${DOCKER_REPO}"
+```
+
+Install Operator Lifecycle Manager:
+
+```bash
+operator-sdk olm install
+```
+
+Create a Catalog Source which points to the operator index image, an operator group and subscription:
+
+```bash
+OPERATOR_INDEX_IMAGE="${DOCKER_REPO}/gchq/gaffer/gaffer-operator-index:${GAFFER_VERSION}"
+
+kubectl apply -f - << EOF
+apiVersion: operators.coreos.com/v1alpha1
+kind: CatalogSource
+metadata:
+  name: gaffer-operator-catalog
+  namespace: olm
+spec:
+  sourceType: grpc
+  image: ${OPERATOR_INDEX_IMAGE}
+  displayName: Gaffer Operator Catalog
+EOF
+
+# Create Operator Group
+kubectl apply -f - << EOF
+apiVersion: operators.coreos.com/v1
+kind: OperatorGroup
+metadata:
+  name: gaffer-operator-group
+  namespace: default
+EOF
+
+# Create subscription
+kubectl apply -f - << EOF
+apiVersion: operators.coreos.com/v1alpha1
+kind: Subscription
+metadata:
+  name: gaffer-operator-subscription
+  namespace: default
+spec:
+  channel: alpha
+  name: gaffer-operator
+  source: gaffer-operator-catalog
+  sourceNamespace: olm
+EOF
+```
+
+Deploy a graph using the examples:
+
+```bash
+./generated/gaffer-operator/bin/kustomize build ./examples/overlays | kubectl apply -f -
+```
+
+Undeploy the graph:
+
+```bash
+./generated/gaffer-operator/bin/kustomize build ./examples/overlays | kubectl delete -f -
+```
