There is several ways to post your docs without wasting money, in a far better way, like using ReadTheDocs or just generating it with whatever library made for your project's language, like Pydoc, and serving it from GitHub Pages.

It's not even complicated, I don't know why keep making it complex…

Never heard about projects using Discord for docs (sounds terrible and useless, tbh), but now I'm afraid of it.

Classic XKCD. I'd pay for a Die Hard version like this.

Well, this is not too strange since we already have a database-related manga.
