+*** =use-package=
+
+#+begin_quote
+A use-package declaration for simplifying your .emacs
+#+end_quote
+
+=use-package= is an awesome utility for managing and configuring
+packages in a neatly organized way and without compromising on
+performance. So let's install it using =striaght.el= and have it use
+=straight.el= for installing packages.

+** No littering in =~/.emacs.d=
+
+#+begin_quote
+Help keeping ~/.emacs.d clean
+#+end_quote
+
+By default, even for Emacs' built-in packages, the configuration files
+and persistent data are all over the place. Use =no-littering= to help
+contain the mess.
+

+ `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
+#+end_src
+
+** Custom file (=custom.el=)
+
+I'm not planning on using the custom file much, but even so, I
+definitely don't want it mixing with =init.el=. So, here, let's give
+it it's own file.
+
+#+begin_src emacs-lisp
+(setq custom-file (no-littering-expand-etc-file-name "custom.el"))
+(when (file-exists-p custom-file)
+ (load custom-file))
+#+end_src
+
+** Backups
+
+Emacs' default backup settings aren't that great. Let's use more
+sensible options. See documentation for the ~make-backup-file~
+variable.
