I just tried visiting the Jekyll website to see how to get started, the documentation page has the following under the Getting Started section --
1) Install Ruby, Ruby Gems.
2) Understand what Gem, Gemfiles, Bundler(?) are.
3) Tells me about it's community for some reason.
4) Finally there's a page which tells me how to make a 'Hello World' blog.
5) 10 more pages explaining what Liquid, layouts, includes, datafiles, assets, deployment are.
6) I still don't know how to make a new post.
Most static site generators have too much of cognitive load. I just want a bunch of plain HTML files generated (ideally in <1s + no JS) from a bunch of markdown files, I don't really care for 99% of the features these things have. I would rather spend a few hours a write a simple script to do it myself instead of wading through the documentation looking for the relevant parts.
