This org file is my literate configuration for GNU Emacs, and is

-** Installation
+tangled to [[./init.el][init.el]]. Packages are installed and managed using
+[[https://github.com/emacscollective/borg][Borg]]. Over the years, I've taken inspiration from configurations of
+many different people. Some of the configurations that I can remember
+off the top of my head are:
+
+- [[https://github.com/dieggsy/dotfiles][dieggsy/dotfiles]]: literate Emacs and dotfiles configuration, uses
+ straight.el for managing packages
+- [[https://github.com/dakra/dmacs][dakra/dmacs]]: literate Emacs configuration, using Borg for managing
+ packages
+- [[http://pages.sachachua.com/.emacs.d/Sacha.html][Sacha Chua's literate Emacs configuration]]
+- [[https://github.com/dakrone/eos][dakrone/eos]]
+- Ryan Rix's [[http://doc.rix.si/cce/cce.html][Complete Computing Environment]] ([[http://doc.rix.si/projects/fsem.html][about cce]])
+- [[https://github.com/jwiegley/dot-emacs][jwiegley/dot-emacs]]: nix-based configuration
+- [[https://github.com/wasamasa/dotemacs][wasamasa/dotemacs]]
+- [[https://github.com/hlissner/doom-emacs][Doom Emacs]]
I'd like to have a fully reproducible Emacs setup (part of the reason
why I store my configuration in this repository) but unfortunately out
window manager (via EXWM) and coming from bspwm, I'm too used to
having fast startup times.
+** Installation
+
+To use this config for your Emacs, first you need to clone this repo,
+then bootstrap Borg, tell Borg to retrieve package submodules, and
+byte-compiled the packages. Something along these lines should work:
+
+#+begin_src sh :tangle no
+git clone https://github.com/aminb/dotfiles ~/.emacs.d
+cd ~/.emacs.d
+make bootstrap-borg
+make bootstrap
+make build
+#+end_src
+

*** Smaller fringe
-Set fringe to a small value so we don't have big borders in EXWM, but
-can still see the =diff-hl= colors in the fringe.
+Might want to set the fringe to a smaller value, especially if using
+EXWM. I'm fine with the default for now.
