I use Markdown with Jekyll because it integrates nicely with GitHub Pages and I can run it locally for authoring. There's tons of support for it, as far as I can tell. Jekyll uses Liquid for templating, and it seems pretty good. For layout, I use Minimal Mistakes which has a really nice feel and it's comparatively easy to customize. Once I was through all the layout configuration stuff, it's really just a matter of writing articles and pushing them up to GitHub - rarely fiddle with anything technical these days.
