This personal inventory project hasn’t been updated in a couple years, but looks Ike it could work for what you’re describing.

There’s a “docs team” that hangs out on the NixOS discourse that I’m sure would be happy to have you. They have meeting every couple weeks if you want to say hi & find out what would be a good way to start contributing.

I usually go with characters from the Discworld series. So far I’ve had a Rincewind, Ridcully, Twoflower, Weatherwax, Ponder, Librarian, Luggage, and Hex, plus a router called “The Clacks”. Really ought to get Vimes and crew into the mix, now that I think of it… maybe the next one will be Angua or Carrot.
