# lefthook.yml - git hooks for ego-lite
#
# Enable hooks:
#   cd package/ego-browser && npm install
#
# lefthook is a package/ego-browser devDependency. npm install runs the
# prepare script, which installs hooks into the repository's .git/hooks.
#
# The git root is the repository root, while the JS package lives in
# package/ego-browser. Commands cd into that package when needed.
