 Use the Nix [C API] from Rust.
 
+## Build with `nix-cargo-integration`
+
+The development environment and building with Nix are taken care of by [nix-cargo-integration](https://github.com/90-008/nix-cargo-integration#readme) ([options](https://flake.parts/options/nix-cargo-integration.html)).
+
+The dependency on Nix is taken care of with the [`nix-bindings-rust` flake-parts module]().
+
+Example usage:
+
+```nix
+{
+  outputs =
+    inputs@{ self, flake-parts, ... }:
+    flake-parts.lib.mkFlake { inherit inputs; }
+    {
+      imports = [
+        inputs.nix-cargo-integration.flakeModule
+        inputs.nix-bindings-rust.modules.flake.default
+      ];
+
+      perSystem = { config, pkgs, ... }: {
+        # optional:
+        nix-bindings-rust.nixPackage = pkgs.nix;
+
+        nci.projects."myproject" = {
+          depsDrvConfig = {
+            imports = [ config.nix-bindings-rust.nciBuildConfig ];
+          };
+        };
+      };
+    };
+}
+```
