+#+TITLE: Amr's Modular Emacs Configuration
+#+PROPERTY: header-args :tangle yes
+
+* Configuration Modules
+
+This file loads the modular Emacs configuration files. It should be the primary way Emacs is configured, replacing or integrating with the original `~/.emacs`, `~/.emacs.d/init.el`, `~/.emacs.d/early-init.el`, and `~/.emacs.d/config.el`.
