+### ⚙️ Bootstrap garm-server with garm-provider-k8s for local development
+
+If you need a `garm-server` with a configured [garm-provider-k8s](https://github.com/mercedes-benz/garm-provider-k8s) in your local cluster to spin up some `k8s based runners` for testing, you can do the following:
+
+Clone the `garm-provider-k8s` repo:
+   ```bash
+   $ git clone https://github.com/mercedes-benz/garm-provider-k8s && cd ./garm-provider-k8s
+   ```
+And follow this [guide](https://github.com/mercedes-benz/garm-provider-k8s/blob/main/DEVELOPMENT.md). But `instead` of the `make tilt-up` in the `garm-provider-k8s` repo, execute the folling command. Make sure you are in your `kind-garm-operator` kubernetes context:
+   ```bash
+   $ RUNNER_IMAGE="localhost:5000/runner:linux-ubuntu-22.04-x86_64" make build copy docker-build docker-build-summerwind-runner && kubectl apply -k hack/local-development/kubernetes/
+   ```
+Essentially this does the same as the `make tilt-up` target in `garm-provider-k8s`, but in your local garm-operator cluster. Otherwise, a separate cluster will be spawned with the latest garm-operator release.
