Some cheapskate insists on writing a guide to selfhost <software> on Heroku and wants to add it to the official documentation, promising to maintain it (since none of the other devs are using or planning to use Heroku). I volunteer to give them a chance on grounds of it being high quality and maintained by that person in the future which they both promise.
Our docs are written as markdown files on github.

So here we go:
Starts a pull request: uploads their """guide""" as a docx. The content is completely unformatted, basically just an enumerated list.

Tell them to format it as markdown, suggest using github gists.
They go ahead and copy pasta their unformatted list into a gist.txt "allright i made it into gist for ya"

Tell them that they did not format it as markdown.
"sorry updated it in markdown :P"

I look at the file, it is still raw text in a gist.txt. Maybe a bit more spaced out, not that I would care to notice any changes at this point.

Tell them it is still not markdown and link them to a perfect example of another guide that takes advantage of code fragments for commands etc and is properly rendered since it uses .md

"I updated it to the markdown this time XP Can you give me some suggestions on how it looks?"

"How it looks"... "how it LOOKS"... I click the link for the 5th time and IT IS STILL JUST A RAW FUCKING GIST.

Jfc that person has some serious reading/thinking disability. To imagine them to be proactively keeping their guide up to date in the future is absolutely impossible. At that point I pulled out my support for the request since it was already taking more effort to even get a readable version of guide than I estimated for the whole process of adding it.

Oh, and one of the steps originally suggested in the """guide""" was adding the credentials file into the vcs.
