Why should anyone use this over Jekyll or any of the numerous other static site generators?
I was collaborating with a bunch of people on a website designed to use Jekyll and I got really tired of talking Windows users through the point of installing the whole Ruby environment just so they could generate content. It's a huge hurdle to have to get non-developer users over.
It is more annoying than something like Gutenberg would be though.
I wish GitHub would support other SSGs in the same manner that GitLab does.
