 This repository contains the Nix / NixOS configuration for all of my systems. Start from `flakes.nix` (see [Flakes](https://nixos.wiki/wiki/Flakes)) if you are looking for NixOS configuration. Start from `home.nix` if you are looking for non-NixOS Nix configuration (eg: on macOS).
 
 - `home.nix`: Only install things that are needed in all platforms (VMs, VPS, WSL2, etc.)
-    - TODO: macOS M1 => https://github.com/srid/m1-mac-nix
 - `flake.nix`: Install things I need natively on NixOS desktop & laptop computers
 
 VSCode note: <kbd>Ctrl+Shift+B</kbd> will run effectuate the new configuration (by running `make`).
 
-## Non-NixOS
+
+## Platforms
+
+### NixOS
+
+```
+make nixos
+```
+
+### macOS 
+
+```
+make darwin

+
+### Other Linux distro (home-manager)
 
 TODO: This section needs an update.
