 * Step 6 also installs the custom resource definitions (CRDs) used by the KubeRay operator.
 
+#### Using Local Deployment Script
+
+You can also run the `local_deploy.sh` bash script (located in `ray-operator/hack`) which runs the steps shown above, but deletes and recreates the kind cluster each run for consistency during repeated development.
+
+There are configuable variables in the script, the defaults are shown below:
+
+```bash
+IMAGE_TAG="kuberay-dev"
+KIND_CLUSTER_NAME="kuberay-dev"
+KIND_NODE_IMAGE="kindest/node:v1.24.0"
+```
+
+Additionally, you can run the script with a `-l` or `--logs` to stream the logs of the ray operator to the terminal after installation.
+
 ### Run the operator outside the cluster
 
 This step requires you to switch your working directory to the kuberay project root. If
