@scribe @thibaultamartin there are plenty options. “Non-techies” tend to ignore them.
Folder with markdown or plaintext files and an ssh client for uploading new ones - can’t go simpler. A basic index.html written by that techie friend can then present it in a nicely readable form with a surprisingly little JavaScript.
But then that’s not what you really want. Every really simple solution I stumbled upon over the years died due to the lack of interest.
