The TL;DR looks incorrect! It's Hugo that's beginner friendly, not Jekyll. I had tried Jekyll and Octopress in the past (many years ago) and gave up on static site generation after I couldn't get the Ruby dependency hell to get installed. With Hugo, I had my site running within an hour.

Along the same lines, I found the Go templating language very natural to pick up, probably because I am a Lisp afficionado.

And lastly, you have a typo in the list of markup languages supported for content; Mark -> MMark. And you missed out Org mode in that list.
