Joon is a Jekyll theme that ports the minimalist Roon design originally built for Ghost, giving static-site users a clean, typography-focused blog layout. It runs on Jekyll, takes standard Markdown or HTML posts, and renders them into a single-author blog with a simple, reading-first interface. The theme is maintained on GitHub by vormwald and released under the MIT license, with the original Roon design credited to Sam Soffes and the Ghost Foundation.

serifto theclassof thebodyelement in the layout file. - Custom accent color — links and the top border use an accent color that you can change by editing two values at the very top of

- Ghost users migrating — anyone familiar with the Roon theme on Ghost who wants the same look and feel on a Jekyll-powered static site.
