 Since pipx installs packages in an isolated environment, you won't have to worry about dependency conflicts or polluting your global python environment. `anifetch` will behave just like a native cli tool. You can upgrade your installation with `pipx upgrade anifetch`

+
+### ❄️ NixOS installation via flakes
+
+❄️ Add the anifetch repo as a flake input:
+
+```nix
+{
+    inputs = {
+        anifetch = {
+            url = "github:Notenlish/anifetch";
+            inputs.nixpkgs.follows = "nixpkgs";
+        };
+    };
+}
+```
+
+Remember to add:
+
+```nix
+    specialArgs = {inherit inputs;};
+```
+
+to your nixos configuration, like I've done here on my system:
+
+```nix
+    nixosConfigurations = {
+      Enlil = nixpkgs.lib.nixosSystem {
+        specialArgs = {inherit inputs outputs;};
+```
+
+#### ❄️ As a package:
+
+Add anifetch to your packages list like so:
+
+```nix
+{inputs, pkgs, ...}: {
+    environment.systemPackages = with pkgs; [
+        inputs.anifetch.packages.${pkgs.system}.default
+        fastfetch # Choose either fastfetch or neofetch to run anifetch with
+        neofetch
+    ];
+}
+```
+
+#### ❄️ As an overlay:
+
+Add the overlay to nixpkgs overlays, then add the package to your package list as you would a package from the normal nixpkgs repo.
+
+```nix
+{inputs, pkgs, ...}: {
+    nixpkgs = {
+        overlays = [
+            inputs.anifetch.overlays.anifetch
+        ];
+    };
+
+    environment.systemPackages = with pkgs; [
+        anifetch
+        fastfetch # Choose either fastfetch or neofetch to run anifetch with
+        neofetch
+    ];
+}
+```
+
+The Nix package contains all the dependencies in a wrapper script for the application aside from fastfetch or neofetch, so you should only need to add one of those to your package list as well.
+
+After you've done these steps, rebuild your system.
