Getting to know Prelude

Certainly the best way to understand how Prelude enhances the default Emacs experience is to peruse Prelude's source code (which is obviously written in Emacs Lisp). Understanding the code is not necessary of course. Prelude includes a prelude-mode minor Emacs mode which collects some of the additional functionality added by Prelude. It also adds an additional keymap that binds many of those extensions to keybindings.
