+### With values.yaml
+
+From module version `v1.4.0` we also support the usage of a `values.yaml` file. By default, if you configured the git generator, we will look for a `values.yaml` inside the `values` folder next to the configured argocd application configuration. The `values.yaml` file will be named after the Helm release name (dashes are replaced by underscores).
