In this episode we cover a more technical perspective and discuss how do we go about building a design system from a flow perspective. We will also discuss some tools which can help us build this as well.

Here is another over hyped term. Every company seems to be making one now a days? But what is a design system really? How does it help you create better frontends? Is it really more than just a component library? Will be answering this and more in this episode.
