 ## How to use
 
-Run `vlux <directory>` in the container to search for .yaml files recursively. All files will be validated with `yamllint` and `kubeval`. `kustomization.yaml` files will be built with `kustomize` and the result will be validated again with `kubeval`.

+
+Extra arguments to the script will be passed to `kubeconform`, e.g. `vlux <directory> -ignore-filename-pattern="kustomizeconfig.yaml"`
