+# This is a simple workflow that runs the publisher and copies the output to https://<owner>.github.io/<repo>/index.html
+# Based on the idea by Carl Leitner
+# Change log:
+# 2021-06-18: (JCT): publish default branches to / , other branches branches/<branch>
+# 2021-11-26: (JCT): Reusable workflow
+# 2022-01-28: (JCT): add auto-create gh-pages if it doesn't exist
+# 2023-01-22: (JCT): use checkout action v3, and JamesIves/github-pages-deploy-action@v4
+
+
+# Make sure your repo has a branch called gh-pages
