I bought a keyboard kit recently and to my horror discovered all the “documentation” to build it is on Discord. The creator’s last message was that he was working on other things after losing interest, and was not monitoring it anymore. So all the channels are full of messages asking where he is, what the status is, is he coming back, etc. I had to scroll back through dozens of pages just to find the docs.

Maybe put up a wiki on GitHub or something? Especially if you don’t want to run a forum or plan on dipping. It’s not that hard.
