If you’re on a Unix-like system (i.e. Linux, OS X, BSD), run the following commands to install the SDK:
curl https://knightos.org/install-sdk | bash
On Archlinux, there is an AUR package named
knightos-sdk which you can install with an aur helper like
aurman which does (almost) all the work for you which may save you some time.
The same procedure can be used to update the SDK. Once the SDK is installed, use
knightos --help to see how it works.
