Yes, like it was mentioned on the chat a bit ago, luckily we use open
source which, if not easy for all to find, is at least the definitive
truth – thanks for adding this in our docs now too for our users.

I'd proactively add a reference here, e.g.:

I really would not link to the manpage source directly on GitHub.
I'd either use manpages.debian.org [0] or none at all and refer to the
corosync-doc package, which ships it.
