How to prepare illy coffee?

Excuse me, I'm curious about how one would go about preparing illy coffee properly. Could you please elaborate on the steps needed to ensure the best possible taste and quality? For instance, do I need to use a specific type of coffee maker, grind the beans to a certain consistency, or measure out a precise amount of water and coffee grounds? I'm looking to make the perfect cup of illy coffee at home and would appreciate any guidance you can offer. Thank you in advance for your expertise.
