+## Stop and restart Kyma without reinstalling
+
+Use the `minikube.sh` script to restart the Minikube cluster without reinstalling Kyma. Follow these steps to stop and restart your cluster:
+
+1. Stop the Minikube cluster with Kyma installed. Run: 
+```
+minikube stop
+```
+2. Restart the cluster without reinstalling Kyma. Run: 
+```
+./scripts/minikube.sh --domain "kyma.local" --vm-driver "hyperkit"
+```
+
+The script discovers that a minikube cluster is initialized and asks if you want to delete it. Answering `no` causes the script to start the Minikube cluster and restarts all of the previously installed components. Even though this procedure takes some time, it is faster than a clean installation as you don't download all of the required Docker images.
+
+To verify that the restart is successful, run this command and check if all Pods have the `RUNNING` status:
+
+```
+kubectl get pods --all-namespaces
+```
+
 ## Troubleshooting
 
 If the Installer does not respond as expected, check the installation status using the `is-installed.sh` script with the `--verbose` flag added. Run:

-The purpose of the `installation/scripts/minikube.sh` script is to configure and start Minikube. The script also checks if your development environment is configured to handle the Kyma installation. This includes checking Minikube and kubectl versions. If Minikube is already initialized, the system prompts you to agree to remove the previous Minikube cluster. The script exits if you do not want to restart your cluster.

+- If you plan to perform a clean installation, answer `yes`. 
+- If you installed Kyma to your Minikube cluster and then stopped the cluster using the `minikube stop` command, answer `no`.  This allows you to start the cluster again without reinstalling Kyma. 
 
 Minikube is configured to disable the default Nginx Ingress Controller.
