Packages initialization
Here, we're initializing MELPA, as well as package.el and use-package.

;; Comment/uncomment this line to enable MELPA Stable if desired. See `package-archive-priorities`
;; and `package-pinned-packages`. Most users will not need or want to do this.

Minimal interface
We disable a lot of interface elements, to make the editor more minimal looking.

apps are not started from a shell."

I don't like any visual or sound bell.
(setq ring-bell-function 'ignore)Font
I use the default monospace font, as it allows me to configure it system wide and have everything coherent. We just make it bigger here for readability.
(set-face-attribute 'default nil :height 125)Visual mode
We turn on visual mode, so that lines can wrap nicely and do go beyond my Emacs buffer size.
(visual-line-mode t)Theme
I use catppuccin as my theme, as I find it comfortable to work with (the Frappe flavor).
(use-package catppuccin-theme
:init

I use doom-modeline as my modeline, as I find it really clean and minimal.

I use vertico as my completion framework. It's minimal, fast and tells me all I need to know and even sorts by history.

which-key is a nice little package that allows to have a minibuffer showing which keybinds are available under prefixes.

Pretty bullets and headlines
