 If you don't want to install helm on your cluster and just want to use `kubectl` to install `kubernetes-external-secrets`, you could get the `helm` client cli first and then use the following sample command to generate kubernetes manifests:
 
 ```bash
-$ helm template --output-dir ./output_dir ./charts/kubernetes-external-secrets/
+$ helm template --include-crds --output-dir ./output_dir external-secrets/kubernetes-external-secrets
 ```
 
 The generated kubernetes manifests will be in `./output_dir` and can be applied to deploy `kubernetes-external-secrets` to the cluster.
