+#+TITLE: DT's Doom Emacs Config
+#+AUTHOR: Derek Taylor (DT)
+
+** FONTS
+Doom exposes five (optional) variables for controlling fonts in Doom. Here
+are the three important ones:
+
++ `doom-font'
++ `doom-variable-pitch-font'
++ `doom-big-font' -- used for `doom-big-font-mode'; use this for
+  presentations or streaming.
+
+They all accept either a font-spec, font string ("Input Mono-12"), or xlfd
+font string. You generally only need these two:
+
+#+BEGIN_SRC emacs-lisp
+(setq doom-font (font-spec :family "Mononoki Nerd Font" :size 15)
+       doom-variable-pitch-font (font-spec :family "Mononoki Nerd Font" :size 15))
+#+END_SRC
+
+** DOOM THEME
+#+BEGIN_SRC emacs-lisp
+(setq doom-theme 'doom-palenight)
+#+END_SRC
+
+** ORG MODE
+#+BEGIN_SRC emacs-lisp
+(setq org-directory "~/Documents/org/")
+#+END_SRC
+
+** LINE SETTINGS

+(global-set-key "\C-x\ t" 'toggle-truncate-lines)
+#+END_SRC
+
+** NEOTREE
+Setting the neotree width to be adjustable.
+#+BEGIN_SRC emacs-lisp
+(setq neo-window-fixed-size nil)
+#+END_SRC
+
+** BROWSER (eww)
+Set urls to open in a specific browser.
+#+BEGIN_SRC emacs-lisp
+(setq browse-url-browser-function 'eww-browse-url)
+#+END_SRC
+
+** SPLITS
+Force splits to open on the right
+#+BEGIN_SRC emacs-lisp
+(defun prefer-horizontal-split ()
+  (set-variable 'split-height-threshold nil t)
+  (set-variable 'split-width-threshold 40 t)) ; make this as low as needed
+(add-hook 'markdown-mode-hook 'prefer-horizontal-split)
+#+END_SRC
+
+** FILE MANAGER (dired)
+Image previews in dired
+#+BEGIN_SRC emacs-lisp

+                                             (kbd "k") 'peep-dired-prev-file)

+    (setq emms-source-file-directory-tree-function

+custom-set-faces was added by Custom.
+If you edit it by hand, you could mess it up, so be careful.
+Your init file should contain only one such instance.
+If there is more than one, they won't work right.
