+<code>
+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 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.
