On the page click on the latest successful build to get a download link under build products. If the image has the extension <code>.zst</code>, it will need to be decompressed before writing to installation device. Use <code>nix-shell -p zstd --run "unzstd <img-name>.img.zst"</code> to decompress the image.

Once the file is downloaded, run the following command to install the image onto the SD Card, replace <code>/dev/mmcblk0</code> with the path to the SD card (use <code>dmesg</code> to find it out).

=== Installation steps ===

The .img files can be directly written to a microSD/SD card (minimal recommended size: 4 GB) using dd, once uncompressed from the ZSTD container. The SD card needs to be unmounted first.

Once the NixOS image file is downloaded, run the following command to install the image onto the SD Card, replace <code>/dev/mmcblk0</code> with the path to the SD card (use <code>dmesg</code> to find it out).

<code>

sudo dd if=nixos-sd-image-23.05pre482417.9c7cc804254-aarch64-linux.img of=/dev/mmcblk0

</code>

The base images are configured to boot up with a serial TTY ( RX/TX UART ) @ 115200 Baud. That way you not necessarily have to have a HDMI Display and keyboard.
