+To start dataproc cluster in the development mode run

+The command above will prepare 3 different resources:
+
+- gentropy package
+- cli script
+- cluster setup script
+
+and based on the branch ref (for example `dev`) will create a namespaced folder under GCS (`gs://genetics_etl_python_playground/initialisation/gentropy/dev`) with the three files described above. These files will be then used to create the cluster environment.
