+Emacs Integration
+=================
+
+Similar to the integration for :program:`vim`, there is an integration for
+:program:`emacs`. It can be found at `clang/tools/clang-format/clang-format.el`
+and used by adding this to your `.emacs`:
+
+.. code-block:: common-lisp
+
+  (load "<path-to-clang>/tools/clang-format/clang-format.el")
+  (global-set-key [C-M-tab] 'clang-format-region)
+
+This binds the function `clang-format-region` to C-M-tab, which then formats the
+current line or selected region.
