## Current Goals

- Installation program

## 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.

## Building

The build process dependencies are specified [here](https://github.com/Mintsuki/Jinx/blob/1c40ceb62e09befc5172d1caf53e3e440a19f624/README.md). If you wish to use the ``make img`` option, you will need mtools. All other needed packages will be installed/built on a container.

It is highly recommended you download pre-built packages from the official repository by running ``make download``. This greatly reduces the compilation time as it will only need to build the host tools.

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``
