 # dotfiles
 
-Pragmatic little scripts without much beauty to them.
-They're not tested thoroughly and will fall on their face in most edge cases.
-At worst, at least they're written documentation of what to install and/or do when first setting up a new machine.
-
-They're supposed to be idempotent: when changing a setting, just run them again to apply.
-Downside is speed, upside is safety and simplicity.
-
-Be warned: they make liberal use of `sudo`, global installations, and piping to `sh`, potentially also with root access.
-Not for the faint of heart.
-
-## Usage
-
-Execute the script whose name corresponds to your distribution.
-
-## Context
-
-I used to have these in Ansible, but the overhead and YAML hell of that got too much, in the context of what it is (single-host, rarely-run configuration management).
-Keeping it simple (and ugly...) now.
+Written with Nix, specific to `nix-darwin` and `home-manager`.
