+#+title: Doom Emacs
+
+* What is Doom Emacs?
+[[https://github.com/doomemacs/doomemacs][Doom Emacs]] is a distribution of the [[https://www.gnu.org/software/emacs/][Emacs Text Editor]] designed for [[https://www.vim.org/][Vim]] users. I like to use Emacs due to its extensibility and extra features it is capable of (besides text editing). Some of these extra features include:
+- [[https://orgmode.org/][Org Mode]] (Hierarchical text-based document format)
+- [[https://www.orgroam.com/][Org Roam]] (A second brain / personal wiki)
+- [[https://orgmode.org/][Org Agenda]] (Calendar and todo list)
+- [[https://magit.vc/][magit]] (Git Client)
+
+[[doom.png]]
+
+I have found Emacs to be incredibly efficient, and transferring my workflow to fit inside of Emacs has allowed me to get much more work done.  I primarily use Emacs for writing, note-taking, task/project management and organizing information.
+
+* My Config
+This directory includes my Doom Emacs configuration, which consists of:
+- [[./config.el][config.el]] - Main configuration
+- [[./init.el][init.el]] - Doom modules (easy sets of packages curated by Doom)
+- [[./packages.el][packages.el]] - Additional packages from Melpa (Emacs package manager).
+- [[./doom.nix][doom.nix]] - Loads Nix Doom Emacs and my configuration into my flake when imported
+- [[./themes/doom-stylix-theme.el.mustache][doom-stylix-theme.el.mustache]] - Mustache Doom Emacs template to be used with stylix, requires my [[../../style/stylix.nix][stylix.nix module]] as well
+- A few other [[./scripts][random scripts]]
+
+My full config is a [[./doom.org][literate org document (doom.org)]].

 * Configuration for Doom Emacs
 Doom Emacs is configured via 3 main files, written in Elisp, a dialect of the Lisp programming langauge designed for Emacs. These 3 main files are:

-* My [[./config.el][config.el]]
+Doom Emacs is traditionally installed by cloning the repository ([[https://github.com/doomemacs/doomemacs][https://github.com/doomemacs/doomemacs]]) and running =./bin/doom install=.  I instead install Doom Emacs via Nix Doom Emacs ([[https://github.com/nix-community/nix-doom-emacs][https://github.com/nix-community/nix-doom-emacs]]), which packages Doom Emacs as a Nix derivation.  The advantage to this is that I get more reproducibility and the ability to rollback updates (if anything breaks), but the downside is that every time the config is changed/updated, the entire derivation must be rebuilt from scratch (this is often time-consuming).  I load this as a Nix derivation in my flake using the [[./doom.nix][doom.nix]] module.
