Device driver installation instructions are incomplete

The installation guide gives a link to install device drivers: https://intelpython.github.io/dpctl/latest/beginners_guides/installation.html#system-requirements

But this page https://dgpu-docs.intel.com/ contains instructions for datacenter devices, running in a very narrow subset of supported operating systems.

That page does not explain how to install drivers for consumer-grade devices through more usual means, like apt-get install intel-opencl-icd. There's also no link for windows.
