Jekyll is a command line tool so we have to use the Terminal application on our computer to start, stop, and run Jekyll.

In the GitHub application, click Repository > Open in Terminal.
Or press Control-`.
Run Jekyll
When in Terminal, type the following command:
bundle exec jekyll serve
Jekyll will now be available in your browser at the following URL: http://127.0.0.1:4000.
