+This directory contains various modules for Emacs support.
+
+To make the modules available to Emacs, you should add this directory
+to your load-path, and then require the modules you want. This can be
+done by adding to your .emacs something like this:
+
+  (add-to-list 'load-path ".../git/contrib/emacs")
+  (require 'git)
+  (require 'git-blame)
+
+
+The following modules are available:
+
+* git.el:
+
+  Status manager that displays the state of all the files of the
+  project, and provides easy access to the most frequently used git
+  commands. The user interface is as far as possible compatible with
+  the pcl-cvs mode. It can be started with `M-x git-status'.
+
+* git-blame.el:
+
+  Emacs implementation of incremental git-blame.  When you turn it on
+  while viewing a file, the editor buffer will be updated by setting
+  the background of individual lines to a color that reflects which
+  commit it comes from.  And when you move around the buffer, a
+  one-line summary will be shown in the echo area.
+
+* vc-git.el:
+
+  This file used to contain the VC-mode backend for git, but it is no
+  longer distributed with git. It is now maintained as part of Emacs
+  and included in standard Emacs distributions starting from version
+  22.2.
+
+  If you have an earlier Emacs version, upgrading to Emacs 22 is
+  recommended, since the VC mode in older Emacs is not generic enough
+  to be able to support git in a reasonable manner, and no attempt has
+  been made to backport vc-git.el.
