To generate SystemDS documentation in HTML, navigate to the docs folder, the root directory of the documentation. From there, you can have Jekyll convert the markdown files to HTML. If you run in server mode, Jekyll will serve up the generated documentation by default at http://127.0.0.1:4000. Modifications to *.md files will be converted to HTML and can be viewed in a web browser.

jekyll serve -w
