+# NixOS and Flakes

+The package contains all the required install scripts and dependencies. You can use the flake as:
+
+```nix
+{
+    inputs = {
+        # ...
+        amber.url = "github:Ph0enixKM/Amber";
+    };
+
+    # then later with home manager for example
+    home.packages = [ inputs.amber.packages.${pkgs.system}.default ];
+}
+```
+
+The package is avaiable as `amber-lang` on [nixpkgs](https://github.com/NixOS/nixpkgs/pull/313774).
+
+While developing with Nix, the flake defines all dependencies for `nix develop` (or `direnv` if used).

 ### Windows support
 As windows does not come with bash installed it makes no sense to support it. Please install WSL 2 on your windows machine and install Linux version of Amber compiler inside.
