+#### Directly installing
+
+The `prismlauncher` flake provides a package which you can install along with
+the rest of your packages
 
 ```nix
+# In your flake.nix:
 {
   inputs = {
     prismlauncher.url = "github:PrismLauncher/PrismLauncher";
   };
-
-...
-
-  nixpkgs.overlays = [ inputs.prismlauncher.overlay ]; ## Within configuration.nix
-  environment.systemPackages = with pkgs; [ prismlauncher ]; ##
 }
 ```
 
-To import without flakes use channels:
+```nix
+# And in your system configuration:
+environment.systemPackages = [ prismlauncher.packages.${pkgs.system}.prismlauncher ];
+
+# Or in your home-manager configuration:
+home.packages = [ prismlauncher.packages.${pkgs.system}.prismlauncher ];
+```
+
+#### Using the overlay
+
+Alternatively, you can overlay the prismlauncher version in nixpkgs which will
+allow you to install using `pkgs` as you normally would while also using the
+latest version
+
+```nix
+# In your flake.nix:
+{
+  inputs = {
+    prismlauncher.url = "github:PrismLauncher/PrismLauncher";
+  };
