 * Preamble
 
-I wanted to write my Emacs configuration in [[https://orgmode.org][Org mode]] for a while, but never could quite figure out how.  Finally, I found [[https://github.com/larstvei/dot-emacs][Lars Tveito]]'s config, which does exactly what I want: =init.el= is small and simple, and replaced after the first run, and =init.org= is automatically tangled.  So I'm very excited.
+** Inspiration
+
+I've been inspired by [[https://github.com/larstvei/dot-emacs][Lars Tveito]]'s config, which does exactly what I
+want: =init.el= is small and simple, and is replaced after the first
+run by the tangled contents of this file -- =config.org= -- which is
+furthermore automatically tangled.
+
+** Problems with this setup
+
++ While =config.org= automatically tangles, I can't run =(load-file
+  init.el)= -- it results in an endless loop for some reason.  I might
+  need to look into a hook of some kind.

 ** Tangling
-After the first run, the above ~init.el~ will be replaced by the tangled stuff here.  However, when /this/ file is edited, we'll need to re-tangle everything.  However, nobody has time to do that manually with =C-c C-v t=, /every time/!  Luckily, Emacs is highly programmable.
+
+After first running Emacs with this config, the above snippet will be
+replaced by the result of tangling this file.  However, when we edit
+=config.org=, we'll need to retangle it.  The default keybinding to
+tangle is =C-c C-v t=, which takes a while and is easy to forget.  So
+let's automatically tangle =config.org= on save.

 * Early initiation
-Emacs 27.1+ uses ~early-init.el~, which is evaluated before things like ~package.el~ and other stuff.  So I have a few settings in there.
 
-** Preamble
-Of course, first thing is the modeline.  After that, I set ~load-prefer-newer~ because, well, it /should/.

+Emacs 27.1+ uses =early-init.el= /in addition to/ =init.el=, mostly
+for settings related to packags.  Since I use =straight.el= for
+package management, I need to specify that in this file.

 * Macros

 ** cuss
-I like ~use-package~,  but I don't like doing the weird "pseudo-package" stuff a lot of people do in their emacs configs.  Partially because I have to set ~:straight nil~ on a lot of built-in packages, but also because I think being /that/ obsessive over one interface through the whole config is ... I don't know, short-sighted?
 
-Either way, I /do/ like the ~:custom~ interface that ~use-package~ has, so I've re-implemented it in my own macro.  This way I don't have to worry about whether to ~setq~ or ~custom-set-variable~ or whatever.  Just ~cuss~!
-#+BEGIN_SRC emacs-lisp
+I like =use-package= a lot, but I don't like the weird
+"pseudo-package" things you see with a lot of =use-package= setups
+around the Internet.  They're cludgy, they /don't/ actually, in my
+opinion anyway, make the config any easier to read (how am I supposed
+to know what options are in =mule=, for example?!), and most
+importantly, =straight.el= doesn't really like them that much.
+
+*However*, I really like the =:custom= keyword in =use-package=,
+ enough to implement it as my own macro.  =cuss= will automagically
+ call =custom-set-variable= or =setq=, whichever is best for the
+ variable being tweaked.  I pulled this straight from =use-package=,
+ so I /know/ it works! :P
