+## Fennel
+
+Originally I wrote this configuration in Lua but I decided to switch to Fennel
+in order to make it even more esoteric to the average software developer. I
+hand-wrote a few parts, and migrated all the existing code using
+[antifennel](https://git.sr.ht/~technomancy/antifennel).
+
+Fennel is a Lisp, so you see a lot of S-expressions. It looks really disgusting
+at first, but once you grasp the true naked structure of Lisp code, you begin
+to understand that it's the most powerful language God ever wrought.

+## Nix
+
+This configuration is built around the Nix package manager. In fact it is my
+second attempt to do so. The [first](https://github.com/youwen5/viminal) was
+configured using [Nixvim](https://github.com/nix-community/nixvim). This mostly
+worked, except you often had to escape into raw Lua strings to get precise
+customization.
