+;;; Installation:
+
+;; The recommended way is to use MELPA (http://melpa.org/) or MELPA Stable
+;; (http://stable.melpa.org/). If either is in your `package-archives', do
+;;   M-x package-install RET rainbow-delimiters RET
+;; Otherwise, open `rainbow-delimiters.el' in Emacs and use
+;;   M-x package-install-from-buffer
+;; Any other methods of installation are unsupported.
+
+;;; Commentary:
+;;
+;; Rainbow-delimiters is a "rainbow parentheses"-like mode which highlights
+;; parentheses, brackets, and braces according to their depth. Each
+;; successive level is highlighted in a different color. This makes it easy
+;; to spot matching delimiters, orient yourself in the code, and tell which
+;; statements are at a given level.
+;;
+;; Great care has been taken to make this mode fast. You shouldn't see
+;; any discernible change in scrolling or editing speed while using it,
+;; even in delimiter-rich languages like Clojure, Lisp, and Scheme.
+;;
+;; Usage:
+;;
+;; To toggle the mode in the current buffer:
+;;   M-x rainbow-delimiters-mode
+;; To start the mode automatically in `foo-mode', add the following to your init
+;; file:
+;;   (add-hook 'foo-mode-hook #'rainbow-delimiters-mode)
+;; To start the mode automatically in most programming modes (Emacs 24 and
+;; above):
+;;   (add-hook 'prog-mode-hook #'rainbow-delimiters-mode)
+;;
+;; Customization:
+;;
+;; To customize various options, including the color theme:
+;;   M-x customize-group rainbow-delimiters
+;;
+;; You can specify custom colors by customizing following faces:
+;; - Faces take the form `rainbow-delimiters-depth-N-face', with N being the
+;;   depth. Depth begins at 1, the outermost color. Faces exist for depths 1-9.
+;; - The unmatched delimiter face: `rainbow-delimiters-unmatched-face'.
+;; - The mismatched delimiter face: `rainbow-delimiters-mismatched-face'.
