For tarballs and release assets from this project, see releases.pagure.org/system76-firmware.
If the developers have uploaded one or more tarball(s), you will be able to find them in the release folder.
The CHECKSUMS file contains the checksums (SHA256 and SHA512) of the files uploaded to pagure.
To use this file, simply download it next to the tarball you downloaded and
run sha512sum -c CHECKSUMS
Clone the repository, then use git archive to create a tarball for any tag:
git clone https://pagure.io/system76-firmware.git
cd system76-firmware
git archive --format=tar.gz --prefix=system76-firmware-<TAG>/ -o system76-firmware-<TAG>.tar.gz <TAG>
Replace <TAG> with the tag name (e.g. v1.0.0). For a zip archive use --format=zip and .zip as the output extension.
