 ## Overview
 
 "React Native for Web" is a project to bring React Native's building blocks and

-React Native – unlike React DOM – is a comprehensive UI framework for

-Bringing the React Native APIs and components to the Web allows React Native

+## Why?
+
+React Native is a comprehensive JavaScript framework for building application
+user interfaces. It provides high-level, platform-agnostic components and APIs
+– e.g., `Text`, `View`, `Touchable*`, `Animated`, `StyleSheet` - that simplify
+working with layout, gestures, animations, and styles. The entire React Native
+ecosystem can depend on these shared building blocks.
+
+In contrast, the React DOM ecosystem is limited by the lack of a higher-level
+framework. At Twitter, we want to seamlessly author and share React component
+libraries between different Web applications (with increasing interest from
+product teams for multi-platform solutions). This goal draws together multiple,
+inter-related problems including: styling, animation, gestures, themes,
+viewport adaptation, accessibility, diverse build processes, and RTL layouts.
+
+Almost all these problems are avoided, solved, or can be solved in React
+Native. Central to this is React Native's JavaScript style API (not strictly
+"CSS-in-JS") which avoids the key [problems with
+CSS](https://speakerdeck.com/vjeux/react-css-in-js). By giving up some of the
+complexity of CSS it also provides a reliable surface for style composition,
+animation, gestures, server-side rendering, RTL layout; and removes the
+requirement for CSS-specific build tools.
+
+Bringing the React Native APIs and components to the Web has the added benefit
+of allowing teams to explore code-sharing between Native and Web platforms.
