+The ARMv6 image boots out-of-the-box. The instructions to build an image for ARMv6 are adapted from [[NixOS_on_ARM#Build_your_own_image_natively|here]].
-The ARMv6 image boots out-of-the-box.
+First, create your own configuration in sd-image.nix (adding cross-compiling information if needed):
+<syntaxHighlight lang=nix>
+# save as sd-image.nix somewhere
+{ ... }: {
+  # uncomment for enabling cross compilation
+  #nixpkgs.crossSystem.system = "armv6l-linux";
+  imports = [
+    # This contains the default definition for the sdcard image build
+    <nixpkgs/nixos/modules/installer/sd-card/sd-image-raspberrypi.nix>
+  ];
+  # put your own configuration here, for example ssh keys:
+  #users.users.root.openssh.authorizedKeys.keys = [
+  #   "ssh-ed25519 AAAAC3NzaC1lZDI1.... username@tld"
+  #];
+}
+</syntaxHighlight>
+Then build the image:
+<syntaxHighlight lang=nix>
+$ nix-build '<nixpkgs/nixos>' -A config.system.build.sdImage -I nixos-config=./sd-image.nix
