# This workflow builds every branch of the repository daily at 16:30 UTC, one hour after ublue-os/nvidia builds. | |
# The images are also built after pushing changes or pull requests. | |
# The builds can also be triggered manually in the Actions tab thanks to workflow dispatch. | |
# Only the branch called `live` is published. | |
