With Ruby >= 2.1 installed, run:
gem install jekyll bundler
bundle install
To view the site, run:
bundle exec jekyll serve
Note that images included under site/assets/ should be referred to with
<img src="{{ site.base-url }}/ray/assets/...">. They will not render properly
when serving the site locally, but this is required for getting the paths to
work out on GitHub.
To deploy the site, run (inside the main ray directory):
git subtree push --prefix site origin gh-pages
