1 #+TITLE: System Configuration
2 #+DESCRIPTION: Personal system configuration in org-mode format.
3 #+AUTHOR: Armaan Bhojwani
4 #+EMAIL: me@armaanb.net
7 Welcome to my system configuration! This file contains my Emacs configuration, but also my config files for many of the other programs on my system!
9 I am currently using Emacs 27.2 on Linux, so some settings and packages may not be available for older versions of Emacs. This is a purely personal configuration, so while I can guarantee that it works on my setup, it might not work for you.
11 I chose to create a powerful, yet not overly heavy Emacs configuration. Things like a fancy modeline, icons, or LSP mode do not increase my productivity, and create visual clutter, and thus have been excluded.
13 Another important choice has been to integrate Emacs into a large part of my computing environment (see [[*Emacs OS]]). I use email, IRC, RSS, et cetera, all through Emacs which simplifies my workflow and creates an amazingly integrated environment.
15 Lastly, I use Evil mode. Modal keybindings are simpler and more ergonomic than standard Emacs style, and Vim keybindings are what I'm comfortable with and are pervasive throughout computing.

19 ** Bootstrap straight.el
20 straight.el is really nice for managing package, and it integrates nicely with use-package. It uses the bootstrapping system defined here for installation.
