# Install the repository's git hooks. The commit-message convention hook is
# optional but recommended; it reminds authors to use the
# "[area] Summary" PR-title convention so that squash-merged commits link
# back to their PR (the same behavior as Apache Fluss).
#
# Usage:
#   bash scripts/hooks/install-hooks.sh
