+# NorthStar - Prototyping Design System
 
-## Cloudscape Design System and NorthStar
+NorthStar is an open source design system with reusable React components for rapidly prototyping intuitive, meaningful and accessible user experience. It simplifies your work and ensures consistent, predictable user experience at scale for your customers. With NorthStar, you can focus on innovation and do more with less.
 
-On July 19, 2022, AWS released [Cloudscape Design System](https://cloudscape.design/) as open source. Cloudscape is a solution for building intuitive user experiences. It offers guidelines to create web applications, along with the design resources and front-end components to streamline implementation. While NorthStar is a design system to rapidly prototype user experiences, Cloudscape is a design system that is intended for use in production environments, beyond the prototypal phase.
+Whether you are a developer or a designer, NorthStar will help you delight your customers from inception to prototype.
