#!/usr/bin/env sh

# This hook has a focus on portability.
# This hook will attempt to setup your environment before running checks.
#
# If you would like `pre-commit` to get out of your way and you are comfortable
# setting up your own environment, you can install the manual hook using:
#
#     pre-commit install --manual
#

# This is a work-around to get GitHub for Mac to be able to run `node` commands
