 +core.hooksPath::
 +      By default Git will look for your hooks in the
 +      '$GIT_DIR/hooks' directory. Set this to different path,
 +      e.g. '/etc/git/hooks', and Git will try to find your hooks in
 +      that directory, e.g. '/etc/git/hooks/pre-receive' instead of
 +      in '$GIT_DIR/hooks/pre-receive'.
 ++
 +The path can be either absolute or relative. A relative path is
 +taken as relative to the directory where the hooks are run (see
 +the "DESCRIPTION" section of linkgit:githooks[5]).

 +This configuration variable is useful in cases where you'd like to
 +centrally configure your Git hooks instead of configuring them on a
 +per-repository basis, or as a more flexible and centralized
 +alternative to having an `init.templateDir` where you've changed
 +default hooks.
