build.yml

# General zola build workflow.
# prerequisites:
# - zola writes output to public/
# - variables below set correctly
#
# Note: it is a general limitation of gh-actions can not make the very
# first deploy to gh-pages.  It will seem to work, but not appear on
# the CDN to be online.  You need to go to settings and set the
# gh-pages branch, then future deploys will work.  See
#  https://github.com/marketplace/actions/github-pages-action#%EF%B8%8F-first-deployment-with-github_token
