Design system advice

10 days ago from , UX/UI Designer | Prototyping Designer

Hi, I started to build a design system using Sketch. It’s my first time I’m building a DS for a very complex system, an other designer made the design and I came in the middle just for the design system. I’m trying to built it in the way of Atomic design suggests - first atomics, then molecules, organisms and so on... but I’m having some difficulties, there are plenty of components that are used in the design only once, should I add them to the DS or maybe I should only add the atomics parts to my DS? Also, do you have any real life tips & tricks of how to build a complex DS for a system you didn’t design?
