Because jekyll-scholar isn't in the list of GitHub-sanctioned plugins, we need a workaround. Here it is.

• edit the site on the source branch locally.
• run bundle exec jekyll serve to serve locally during editing.
  • Note: requires ruby version 3, so may need to change the current ruby version (e.g. chruby 3.1.7 or rvm use 3.1.7 --- note, tested with v3.4.5 and it didn't work. use 3.1.7).

When ready, git push to put the edits on the GitHub.

• First time may need to set source: git push --set-upstream origin source

./bin/deploy --user

Answer y.

• This will build the site from source branch (bundle exec jekyll build ) and put the resulting site on the master branch, where github pages will find it and serve it at jahoo.github.io
