+
+Note: this design system is not used in Storybook's UI. The stack is different and theming requirements of Storybook add complexity beyond the scope of this project. However, Storybook's visual design is identical to what's here.

+## Tech stack
+Building components
+- 📚 [Storybook](https://storybook.js.org) for UI component development and [auto-generated docs](https://medium.com/storybookjs/storybook-docs-sneak-peak-5be78445094a)
+- 💅 [Styled-components](https://www.styled-components.com/) for component-scoped styling
+- ⚛️ [React](https://reactjs.org/) declarative component-centric UI
+
+Maintaining the system
+- 📦 [NPM](https://www.npmjs.com/) for [packaging and distribution](https://blog.hichroma.com/how-packaging-makes-it-dead-simple-to-share-ui-components-29912593539d)
+- ✅ [Chromatic](https://www.chromaticqa.com/) to prevent UI bugs in components (by Storybook maintainers)
+- 🚥 [CircleCI](https://circleci.com/) Continuous integration
+
+## Why 
+The Storybook design system codifies existing UI components into a central, well-maintained repository. It is built to address having to paste the same components into multiple projects again and again. This simplifies building UI's with Storybook's design patterns.  
+
+#### What we're doing
+- Build and maintain a design system in the open
+- Share UI components between multiple apps 
+- Dogfood upcoming Storybook features 
+- Welcome contributors of all levels and backgrounds
+
+
+#### What we're not doing
+- Rewrite all new components from scratch
+- Overhaul the visual design of components
+- Typescript (the consumer apps don't use it)
+- Compete with more general design systems like ANT or Material.
