 There are two approaches to delete objects managed by `kubectl apply`.
 
-### Recommended: `delete -f <filename>`
+### Recommended: `kubectl delete -f <filename>`

 ```shell
-delete -f <filename>
+kubectl delete -f <filename>
 ```
 
 ### Alternative: `kubectl apply -f <directory/> --prune -l your=label`
