 As kernelci-api relies on other deployments, it is important to get them up and running first and get kernelci-api up and running afterwards. Thus after completing all the above steps, you can apply ```api-deployment.yaml``` file that is present in the root of kube/minikube folder. To apply the YAML file in the minikube cluster, simply run
 ```
-kubectly apply -f api-deployment.yaml
+kubectl apply -f api-deployment.yaml
 ```
 
 ## Cleaning up everything afterwards
 
-To clean up everything simply use the ```clean-all.sh``` script provided in the root of the kube/minikube/hack folder by running

 This script would also do the clean up and will deploy everything afresh. But it can be time-consuming to deploy everything afresh, so if you want to reconfigure some deployment maybe because the image is updated, just reapply that deployment or do the rolling update instead of running this script.
