+GitHub CI
+=========

+The GitHub CI action needs AWS creds and an existing S3 bucket.
+These creds and the bucket name are injected via repository-scoped Actions `secrets <https://github.com/lsst-sqre/ltd-conveyor/settings/secrets/actions>`_ and `variables <https://github.com/lsst-sqre/ltd-conveyor/settings/variables/actions>`_
