# This script aims at helping create a PR to update the manifests of knative.
|

# This script:
|
|
# 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
