+
+;;; Commentary:
+;; This file is in the public domain.
+;;
+;; If you want to give this file a try, you can just drop it into
+;; ~/.emacs.d: it downloads everything it needs. It is also relatively
+;; fast to start up (once it's downloaded all the required packages),
+;; as it endeavours to load packages lazily when possible.
+;;
+;; A general note on keybindings: the custom keybindings applicable to
+;; all major modes appear with the C-c prefix, as is standard.
+;; Per-language commands appear with the C-c a prefix. The most
+;; important keybinding, C-;, provides counsel-M-x, which lets you
+;; fuzzy-find through the space of available functions. Exploring
+;; counsel-M-x is the best way to become familiar with the space of
+;; extensible functions, which is a sine qua non for being comfortable
+;; with Emacs.
