This is using GitHub pages; just push to publish.
To contribute, many pages can be simply added and edited using the GitHub UI - this is encouraged as it's quicker for many.
If one is working on the theming or any new features that needs double-checking on how Jekyll compiled it, it's encouraged to spin this up locally and test. It's easy!
bundle - Ruby Dependency Manager (install with gem install bundler - may require sudo)bundle install
Compile, serve, & watch:
bundle exec jekyll serve
Other commands:
bundle exec jekyll --help
