Start using home-manager and nix-darwin

* Created Makefile to manage install/uninstall
* Created my first flake containing basics

Installed the basics from Nix pkgs and linked their configs out of
the `files` directory, one day to be replaced with something more
Nix-native:

* zsh
* tmux
* neovim

 My dot-files.
 
+I use [Rake](https://ruby.github.io/rake/) to manage my dot-files. It uses [Homebrew](https://brew.sh/) to install packages and Ruby to install dot-files and/or perform any extra customisations.
+
+I'm in the process of moving to a [nix-based setup](https://nixos.org/explore.html) -- using [nix-darwin](https://github.com/LnL7/nix-darwin) and [Home Manager](https://github.com/nix-community/home-manager) -- to replace this home-grown solution.
+
+If this setup is new to you, these resources helped me:
+
+* [Home Manager Manual](https://nix-community.github.io/home-manager/)
+* [Migrating from Homebrew to Nix for OSX](https://discourse.nixos.org/t/migrating-from-homebrew-to-nix-for-osx/2892)
+* [Declarative macOS Configuration Using nix-darwin And home-manager](https://xyno.space/post/nix-darwin-introduction)
+* [Setup nix, nix-darwin and home-manager from scratch on an M1 Macbook Pro](https://gist.github.com/jmatsushita/5c50ef14b4b96cb24ae5268dab613050)
+* [How to Learn Nix, Part 19 Switching from Homebrew to Nix](https://ianthehenry.com/posts/how-to-learn-nix/switching-from-homebrew-to-nix/)
+
+I probably should've learned how to use Nix the current way, but instead I've started using the [experimental Flake method](https://nixos.wiki/wiki/Flakes). This will no doubt get some major rewrites as I learn how nix, flakes and the different modules work together.
