-- For NixOS configurations you generally care only about the `Size` (closure size/size on disk).
+- For NixOS/Home-Manager configurations you generally care only about the `Size` (closure size/size on disk).
   - Reduce the `Size` by disabling unneeded services/default packages.
 - For Packages you care about both the `Size` and the `NAR Size`.
   - Reduce the `NAR Size` by reducing the size of the build outputs, e.g. don't copy unnecessary data to the $out dir, optimize binaries for size, etc.
