Hmm, is this "hard links" feature implemented? If not, then this
documentation is a bit outdated.

Following the example of af189b4 (Documentation/git-worktree: split
technical info from general description, 2015-07-06), it might be a
good idea to keep this high-level overview free of such low-level
details and instead mention $GIT_DIR/worktrees/<id>/gitdir in the
"DETAILS" section.

Perhaps something like this, on top of your patch (assuming that the
"hard links" feature is not implemented):
