+```
+
+#### Parameters
+
+- **chart_name**: The directory in the source repository where the installable chart should be found.
+- **release_version**: The version of the release (*default: v1.0.0*)
+- **release_name**: The name of the release (*default: helm-release*)
+- **release_namespace**: The namespace in which the release is to be installed (*default: ""*)
