## Building
The build process only needs xorriso, curl, zstd, fakeroot and bsdtar on the host. If you wish to use the ``make img`` option, you will need mtools. All other needed packages will be installed/built on the container.
To build the project, run ``make``. This will create a file named ``astral.iso``
After this, if you wish to create an ext2 disk image, run ``make disk``
## Running
If you built it from source, run ``make run-kvm`` or ``make run-disk-kvm``
There are prebuilt images and instructions at https://astral-os.org/about.html.
