# Purge the CloudFlare cache after pushing an update to GitHub Pages
#
# To use, rename this file to "post-receive" and drop it into the `.git/hooks/` directory in your project's root.
# Change the $branch value based on the type of page you're deploying.
# Use "master" for Organization Pages, and "gh-pages" for Project Pages.
#
# Find your CloudFlare API token here: https://www.cloudflare.com/a/account/my-account
