Hi,
I actually use git to track my sites. You need to confige the correct folders and it work good.
However, there is one breaking point. it’s the SQLite database. this is just binary data from git perspective. So parallelly adding new posts is difficult.
So Multiuser/Computer is possible, but you cannot parallely work on the blog posts.
Also be careful not to upload passwords for your website to public git repos.
