+=== Using cross-compiled packages in the host NixOS config ===
+First, configure your builder as a trusted [[Binary Cache|binary cache]].
+Then copy the cross-compiled package to the host using <code>nix copy</code>.
+Finally modify your <code>configuration.nix</code> as follows:
+<syntaxhighlight lang="nix">
+let pkgsCross = import <nixpkgs> {
+  localSystem = "x86_64-linux"; # <-- put your builder's platform here and below
+  hostSystem = "x86_64-linux";
+  crossSystem = "aarch64-linux"; # <-- put your host's platform here
+};
+in
+{
+  environment.systemPackages = [
+    pkgsCross.hello # <-- put your cross-compiled package here
+  ];
+}
