	# Dependency Review Action
	#
	# This Action will scan dependency manifest files that change as part of a Pull Request,
	# surfacing known-vulnerable versions of the packages declared or updated in the PR.
	# Once installed, if the workflow run is marked as required,
	# PRs introducing known-vulnerable packages will be blocked from merging.
