|

# # 1. Checks out a new branch
|
|
# # 2. Download files into the correct places
|
|
# # 3. Commits the changes
|
|
# #
|
|
# # Afterwards the developers can submit the PR to the kubeflow/manifests
|

# # repository, based on that local branch
|

# # It must be executed directly from its directory
