I have done an evening of https://docs.jade.fyi code maintenance. I updated the nixpkgs version to the latest unstable from today, and released new docs for octave, grep, gforth, gnu cobol, time, and poke (the hex editor!)
This web site is my love letter to everyone else sick of info(1): it's single page ctrl-f compatible docs for most gnu software you've heard of, as well as postgres, and zsh, with pleasant CSS.
