The documentation is stored as Markdown files, but sometimes it can be useful to run these locally. The docs are served using Jekyll, and require Ruby >2.4.0 and Bundler:

``bash
gem install jekyll bundler
`

The docs can be built locally and served with live reload:

`bash
npm run docs:install
npm run docs:start
