+## Use a formatter (e.g. hindent, ormolu/formolu)
+Put the following code in your init file to bind `C-c C-f` to format
+the code in the selected region using
+[ormolu](https://hackage.haskell.org/package/ormolu). You can adjust
+this to use another formatter.
+
+```
+(defun format-haskell (start end)
+ (interactive "r")
+ (let ((file (or buffer-file-name (error "Need to be visiting file")))
+ (text (buffer-substring-no-properties start end)))
+ (shell-command-on-region start end (concat "ormolu --stdin-input-file "
