   brittany built in.
 #### Atom
   [Atom Beautify](https://atom.io/packages/atom-beautify) supports brittany as a formatter for Haskell. Since the default formatter is set to hindent, you will need to change this setting to brittany, after installing the extension.
+#### Emacs
+  The following is an easy way to use `brittany` in Emacs
+```
+(defun brittany-format-buffer-file ()
+  "run brittany command on the current file and revert the buffer"
+  (interactive)
+  (save-buffer)
+  (shell-command
+   (format "brittany %s --write-mode=inplace"
+           (shell-quote-argument (buffer-file-name)))
+   nil
+   shell-command-default-error-buffer)
+  (revert-buffer t t t))
+
+(add-hook 'haskell-mode-hook
+          (lambda ()
+            (local-set-key (kbd "C-c C-f") 'brittany-format-buffer-file)))
+```
