### How to configure elpaca (package manager)
[Add the elpaca bootstrap code](https://github.com/progfolio/elpaca?tab=readme-ov-file#installer) to `~/.emacs.d/pre-init.el`:
``` elisp
(defvar elpaca-installer-version 0.8)
(defvar elpaca-directory (expand-file-name "elpaca/" user-emacs-directory))
(defvar elpaca-builds-directory (expand-file-name "builds/" elpaca-directory))
(defvar elpaca-repos-directory (expand-file-name "repos/" elpaca-directory))
(defvar elpaca-order '(elpaca :repo "https://github.com/progfolio/elpaca.git"
:ref nil :depth 1
:files (:defaults "elpaca-test.el" (:exclude "extensions"))
:build (:not elpaca--activate-package)))
(let* ((repo (expand-file-name "elpaca/" elpaca-repos-directory))
(build (expand-file-name "elpaca/" elpaca-builds-directory))
(order (cdr elpaca-order))
(default-directory repo))
(add-to-list 'load-path (if (file-exists-p build) build repo))
(unless (file-exists-p repo)
(make-directory repo t)
