I don't recall the history exactly but hand-wavingly I think it probably started with the wiki and then that was clumsy to link to and a web site was set up, probably with the intention to replace the Github wiki
though there are some administrative things which probably still make more sense in the wiki
hehe ok, anyways, I gotta look at the little ones for a while, I made a fork of the actual repository, will load it up into VS code later and see what I can do
