Hello,
I’ve put together a (simple) sample (static) website called Hello, Pages! (Source) using the latest and greatest built-in Jekyll plugins e.g. Optional Front Matter, README Index, Default Layout, and Titles from Headings that let you publish pages on GitHub without any configuration or front matter blocks e.g. just add some pages in plain text with markdown formatting. That’s it.
Happy publishing w/ Jekyll. Cheers.
PS: Bonus: I’ve added the Hello, Pages! V2 (Source) sample w/ custom layout, github banner, footer (w/ build time) and more.
