 # viminal2
 
-This is my second attempt at creating a Neovim configuration intended for
-NixOS. 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.
+This is my Neovim configuration, written in [Fennel](https://fennel-lang.org/),
+a Lisp that transpiles to Lua. This allows me to continue Vimming while
+masquerading as an Emacs lisper, walking the fine line between the light and
+dark sides of text editing.
+
+## 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.

+                                          (vim.cmd "tabdo wincmd =")
+                                          (vim.api.nvim_set_current_tabpage current-tab))
+                              :desc "Resize splits with terminal window"
+                              :group (vim.api.nvim_create_augroup :EqualizeSplits

+```

+## 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.

 You can test drive the configuration (even if you aren't on NixOS) if you have
 the Nix package manager available (with flakes).
