	;;
	;; - `doom-font' -- the primary font to use
	;; - `doom-variable-pitch-font' -- a non-monospace font (where applicable)
	;; - `doom-big-font' -- used for `doom-big-font-mode'; use this for
	;;   presentations or streaming.
	;; - `doom-unicode-font' -- for unicode glyphs
	;; - `doom-serif-font' -- for the `fixed-pitch-serif' face
	;;
	;; See 'C-h v doom-font' for documentation and more examples of what they
	;; accept. For example:
	;;
	default-font "Source Code Pro"
	default-font-size 14.0
	;; If you or Emacs can't find your font, use 'M-x describe-font' to look
	;; them up, `M-x eval-region' to execute elisp code, and 'M-x
	;; doom/reload-font' to refresh your font settings. If Emacs still can't
	;; find your font, it likely wasn't installed correctly. Font issues are

;; Whenever you reconfigure a package, make sure to wrap your config in an
;; `after!' block, otherwise Doom's defaults may override your settings. E.g.
;;
;;   (after! PACKAGE
;;     (setq x y))
;;
;; The exceptions to this rule:
;;
;;   - Setting file/directory variables (like `org-directory')
;;   - Setting variables which explicitly tell you to set them before their
;;     package is loaded (see 'C-h v VARIABLE' to look up their documentation).
;;   - Setting doom variables (which start with 'doom-' or '+').
;;
;; Here are some additional functions/macros that will help you configure Doom.
;;
;; - `load!' for loading external *.el files relative to this one
;; - `use-package!' for configuring packages
;; - `after!' for running code after a package has loaded
;; - `add-load-path!' for adding directories to the `load-path', relative to
;;   this file. Emacs searches the `load-path' when you load packages with
;;   `require' or `use-package'.
;; - `map!' for binding new keys
;;
;; To get information about any of these functions/macros, move the cursor over
;; the highlighted symbol at press 'K' (non-evil users must press 'C-c c k').
;; This will open documentation for it, including demos of how they are used.
;; Alternatively, use `C-h o' to look up a symbol (functions, variables, faces,
;; etc).
;;
;; You can also try 'gd' (or 'C-c c d') to jump to their definition and see how
;; they are implemented.
