Note: I’m building this locally on WSL.
Add new content, then build the site…
bundle exec jekyll build
The new post should now be visible on the filesystem under _site.
We can test how this looks for real by running the site locally:
bundle exec jekyll serve
Commit to master and push up. There are github actions that build and deploy.
See https://pages.github.com/versions/ for supported package dependencies. To update in the repo run
bundle update github-pages
