# This action adds checklists from .github/pr-checklists/
# to PR conversations
# when a PR is targeted at a specific branch (branches)
# and a specific label (labels) are assigned.
#
# Checklist file name must match label name and end with '.md' extension.
#
# This action uses:
# - actions/checkout@v3
# - oleksiyrudenko/pr-comment@v1.1 (an updated fork of machine-learning-apps/pr-comment@master)
