+** Changing theme
+Although this module uses the ~doom-one~ theme by default, [[https://github.com/hlissner/emacs-doom-theme/][doom-themes]] offers a number of alternatives:
 
-+ ~:font~ :: the default font.
-+ ~:big-font~ :: the font to use when ~doom-big-font-mode~ is enabled.
-+ ~:variable-font~ :: the font to use when ~variable-pitch-mode~ is active (or where the ~variable-pitch~ face is used).
-+ ~:unicode-font~ :: the font used to display unicode symbols. This is ignored if the =:ui unicode= module is enabled.
++ *doom-one:* doom-themes' flagship theme, inspired by [[https://atom.io/][Atom's]] One Dark themes
++ *doom-vibrant:* a more vibrant version of doom-one
++ *doom-molokai:* based on Textmate's monokai
++ *doom-nova:* adapted from [[https://trevordmiller.com/projects/nova][Nova]]
++ *doom-one-light:* light version of doom-one
++ *doom-peacock:* based on Peacock from [[https://daylerees.github.io/][daylerees' themes]]

+This can be changed by changing the ~doom-theme~ variable, e.g.
 
 #+BEGIN_SRC emacs-lisp
-;; These are the defaults of this module
-(set! :font "Fira Mono" :size 12)
-(set! :big-font "Fira Mono" :size 18)

+** Changing fonts
+core/core-ui.el has four relevant variables:
+
++ ~doom-font~ :: the default font to use in Doom Emacs.
++ ~doom-big-font~ :: the font to use when ~doom-big-font-mode~ is enabled.
++ ~doom-variable-font~ :: the font to use when ~variable-pitch-mode~ is active (or where the ~variable-pitch~ face is used).
++ ~doom-unicode-font~ :: the font used to display unicode symbols. This is ignored if the =:ui unicode= module is enabled.
