 Generates a `kustomization.yaml` file, optionally providing the ability to run commands (e.g. `helm template`) on your OS prior to generating a kustomization, and will compose the kustomization fields that deal with file paths (e.g. `resources`) with glob-like features, as well as pass-through all other kustomization configuration properties. No need to explicitly enumerate every file to be 'kustomized' individually.
 
-Takes a config file as input, telling **Helmizer** if you want to run any commands. Then if you give it one or more directories for `crds`/`components`/`patchesStrategicMerge`/`resources`, it will recursively lookup all of those files and render them into your kustomization.yaml. Want to skip including one file like `templates/secret.yaml`? Just add the relative path to `helmizer.ignore` to `helmizer.yaml`.
