How to create UI Kits?

I do about 10 years of design for websites and applications. I usually have to order a certain amount of work on the website or app of a particular subject. The other day knocked a potential customer who wants to order ui kit, with consults with me what theme and what screens. In General, do not quite understand where to start and which side to approach. Perhaps there are some standards or rules or wishes, on the basis of which to make ui kits?
