#+TITLE: Nyxt Configuration
#+PROPERTY: header-args:lisp :tangle ~/dotfiles/guix/home/files/nyxt/init.lisp :mkdirp yes

Nyxt is a browser written in Common Lisp that follows the same philosophy of extensibility as Emacs. This makes it a perfect companion to an Emacs centered eco-system when you need a browser with more features than Eww or w3m.
