 * Description
-This module modifies Emacs' user interface.
+This module gives Doom its signature look: powered by the =doom-one= theme
+(inspired by Atom's One Dark theme) and =solaire-mode=.
 
-Doom's look is loosely inspired by Atom's One Dark theme, and is largely contained in the] plugin.

 ** Strange font symbols
-If you're seeing strange unicode symbols, this is likely because you don't have ~all-the-icons~'s font icon installed. You can install them with ~M-x all-the-icons-install-fonts~.

+** Ugly background colors in tty Emacs for daemon users
+=solaire-mode= is an aesthetic plugin that makes file-visiting buffers brighter
+than the rest of the Emacs' frame (to visually differentiate temporary windows
+or sidebars from editing windows). This looks great in GUI Emacs, but can look
+questionable in the terminal.
+
+It disables itself if you start tty Emacs with ~emacs -nw~, but if you create a
+tty frame from a daemon (which solaire-mode cannot anticipate), you'll get an
+ugly background instead.
+
+If you only use Emacs in the terminal, your best bet is to disable the
+solaire-mode package:
+
+#+BEGIN_SRC elisp
+;; in ~/.doom.d/packages.el
+(package! solaire-mode :disable t)
+#+END_SRC
