+## NixOS installation
+
+With flakes enabled, a sample installation will look like this:
+
+```nix
+# flake.nix
+{
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+    home-manager = {
+      url = "github:nix-community/home-manager";

+    };
+
+    hyprland.url = "github:hyprwm/Hyprland";
+    split-monitor-workspaces = {
+      url = "github:Duckonaut/split-monitor-workspaces";
+      inputs.hyprland.follows = "hyprland"; # <- make sure this line is present for the plugin to work as intended
+    };
+  };
+
+  outputs = {
+    self,
+    nixpkgs,
+    home-manager,
+    split-monitor-workspaces,
+    ...
+  }: let

+    #        ↑ Swap it for your system if needed
+    pkgs = nixpkgs.legacyPackages.${system};
+  in {
+    nixosConfigurations = {
+      yourHostname = nixpkgs.lib.nixosSystem {
+        system = "x86_64-linux";
+        modules = [
+          # ...
+          home-manager.nixosModules.home-manager
+          {
+            home-manager = {
+              useGlobalPkgs = true;
+              useUserPackages = true;
+              users.yourUsername = {
+                wayland.windowManager.hyprland = {
+                  # ...
+                  plugins = [
+                    split-monitor-workspaces.packages.${pkgs.system}.split-monitor-workspaces

+          }

+        # ...
+      };
+    };
+  };
+}
+```
+
+You will need to have home-manager installed and configured. You use `wayland.windowManager.hyprland.plugins = [];` to add the plugin. The home-manager
+module will handle the rest.
 
 # Usage
+
 The plugin provides drop-in replacements for workspace-related commands
+
 | Normal                | Replacement                   |
 |-----------------------|-------------------------------|
 | workspace             | split-workspace               |
