# Note that build.yml from develop will be used even for PR builds

    # We allow builds:
    # 1) When triggered manually
    # 2) When it's a merge into a branch
    # 3) For PRs that are labeled as build and
    #  - It's a code change
    #  - A build label was just added
    # A bit complex, but prevents builds when other labels are manipulated
