 Most problems, however, can be fixed by `M-x load-file ~/.emacs.d/init.el` once more. This fixes problems caused by weird states during intiialization.
 Alternatively you can always debug further or use `package-install` to install packages you care about.
 
+## Customization

+The `elisp` directory contains all associated emacs lisp files. In particular `keybinds.el` contains the default keybinds. There are other mode
+settings that can be left alone assuming you keep the default packages. Theming and other UI elements can be customized in `ui.el`. The general
+philosophy is to keep the emacs lisp as modular as possible to make it as maintainable as possible. Keybinds are adjusted sparingly and most
+are left with the plugin defaults.
+
+You will notice this project makes heavy use of `use-package`. I would recommend keeping it this way.
