+### Motivation
+
+This repository is a bit of a meme. The meme is that my neovim is configured by
+a Lisp, similar to emacs. The Lisp used is [fennel][Fennel] which transpiles
+directly to Lua. I am using a tool called [aniseed][Aniseed] to automatically
+convert Fennel to Lua. Lastly, I use [nix][Nix] to bootstrap Aniseed.
+
+The configuration itself is rather close to the original
+[kickstart][kickstart.nvim] repository. I added some utility from my original
+neovim configuration and added my LSP configuration.
+
+### Installation
+
+```
+nix build                  # builds `init.vim`
+ln -s result/init.vim      # reads fnl/ converts to lua/
+vim -s ":PackerInstall"    # bootstrap packer
+vim -s ":PackerInstall"    # install plugins
+```
