How to redefine the allout prefix keybinding

Question

The allout mode document says,

We recommend customizing allout-command-prefix to use just \C-c as the command prefix, if the allout bindings don't conflict with any personal bindings you have on \C-c.

I don't like to customize the variable, but like to configure it instead (I think \C-c\C-c is a better option). How can I do that?

UPDATE:

I tried the suggested solution like the following in my init, and it works great.

(defun my-allout-mode-hook ()
      (setq allout-command-prefix (kbd "C-c C-c"))
      )

    (add-hook 'allout-mode-hook 'my-allout-mode-hook)

(setq allout-command-prefix (kbd "C-c C-c"))

I know nothing about use-package, so I'll leave that part to you.

C-c C-c is almost certainly going to conflict with other things. It's a very common binding for taking some kind of action in a buffer.

You can safely use C-c <letter> for any upper- or lower-case letter. Those sequences are reserved for end-users.

Another question, how to enable the allout minor mode on Emacs starts for all modes?

You can create a global version of the minor mode like so:

(defun my-turn-on-allout-mode-maybe ()
  "Enable `allout-mode', where applicable."
  ;; Unconditional here, but edit as desired if it turns out
  ;; that you don't actually want this for ALL modes.
  ;; (This function is called in every buffer, when the
  ;; global mode is enabled.)
  (allout-mode 1))

(define-globalized-minor-mode my-global-allout-mode allout-mode
  my-turn-on-allout-mode-maybe
  :group 'allout)

(my-global-allout-mode 1)

(but you should really post separate questions as separate questions.)
