Thread:Project:Support desk/MediaWiki unable to find diff3 and Git during installation/reply (4)

> MediaWiki itself does not use Git at all.

Correct :)

> Git is (only?) used to show version information

No :) The version information is extracted out of the git meta data directory ".git", which can be read as "normal" files without to have git installed. So, the version information is visible, when you haven't installed git, too. All you need is the .git directory (or at least the HEAD file in .git/ iirc) :)

> I think there also was such a setting for the path to Git

Hmm, the only one i know is Manual:$wgGitRepositoryViewers, which stores the valid git repositories to link to (in Special:Version).
