Most modules are not currently documented. Helping out with their documentation is a great way to contribute to the project!

Prelude provides extra functionality through modules. Some modules may require extra steps to enable all functionality. These steps and the functionality provided by these modules are documented on the following links.

What's a module?

Prelude modules are plain old Elisp libraries - there's absolutely nothing magical about them. Most of them simply install a few Emacs packages and provide some sensible baseline configuration for them. Here's a real example.

;;; prelude-ruby.el --- Emacs Prelude: A nice setup for Ruby (and Rails) devs.
;;; Code:

(require 'prelude-programming)

(prelude-require-packages '(inf-ruby yari))

;; We never want to edit Rubinius bytecode
(add-to-list 'completion-ignored-extensions ".rbc")

(define-key 'help-command (kbd "R") 'yari)

(with-eval-after-load 'ruby-mode
  (defun prelude-ruby-mode-defaults ()
    (inf-ruby-minor-mode +1)
    ;; CamelCase aware editing operations
    (subword-mode +1))

  (setq prelude-ruby-mode-hook 'prelude-ruby-mode-defaults)

  (add-hook 'ruby-mode-hook (lambda ()
                              (run-hooks 'prelude-ruby-mode-hook))))

(provide 'prelude-ruby)
;;; prelude-ruby.el ends here

To use a module you simple have to require it. No new concepts. No magic.
