Build and install

You'll need flatpak-builder and the matching Flatpak SDK. Then clone the repository and build:

git clone https://github.com/maybejaishkhan/regulus
cd regulus
flatpak-builder --force-clean --user --install --ccache build-dir packages/flatpak/dev.jaish.Regulus.yml
flatpak run dev.jaish.Regulus

First run

Pick Windows 11 or Windows 10 IoT Enterprise LTSC, choose a preset, and let Regulus download the image and set up Windows for you. The first run takes a while, since it's a full Windows install.

What you need

Regulus needs hardware virtualization. Your CPU has to expose Intel VT-x or AMD-V, and Linux has to give Regulus access to /dev/kvm. If you're not sure whether it's on, the enable virtualization guide walks through it.
