 ## Overview
 
 "React Native for Web" is a project to bring React Native's building blocks and
-touch handling to the Web.
+touch handling to the Web. [Read more](#why).
 
-React Native – unlike React DOM – is a comprehensive UI framework for
-application developers. React Native's components are higher-level building
-blocks than those provided by React DOM. React Native also provides
-platform-agnostic JavaScript APIs for animating and styling components,
-responding to touch events, and interacting with the host environment.
-
-Bringing the React Native APIs and components to the Web allows React Native
-components to be run on the Web platform. But it also solves several problems
-facing the React DOM ecosystem: no framework-level animation or styling
-solution; difficulty sharing and composing UI components (without pulling in
-their build or runtime dependencies); and the lack of high-level base
-components.

+## Why?
+
+There are many different teams at Twitter building web applications with React.
+We want to share React components, libraries, and APIs between teams…much like
+the OSS community tries to do. At our scale, this involves dealing with
+multiple, inter-related problems including: a common way to handle style,
+animation, touch, viewport adaptation, accessibility, themes, RTL layout, and
+server-rendering.
+
+This is hard to do with React DOM, as the components are essentially the same
+low-level building blocks that the browser provides. However, React Native
+avoids, solves, or can solve almost all these problems facing Web teams.
+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.

+To support right-to-left languages, application layout can be automatically
+flipped from LTR to RTL. The `I18nManager` API can be used to help with more
+fine-grained control and testing of RTL layouts.
+
+React Native for Web provides an experimental feature to support "true left"
+and "true right" styles. For example, `left` will be flipped to `right` in RTL
+mode, but `left$noI18n` will not. More information is available in the `Text`
+and `View` documentation.

+## Working with icons and images
+
+Icons and images that must match the LTR or RTL layout of the app need to be manually flipped.
+
+Either use a transform style:
+
+```js
+<Image
+  source={...}
+  style={{ transform: [{ scaleX: I18nManager.isRTL ? -1 : 1 }] }}
+/>

+
+Or replace the source asset:

-Pseudo-classes like `:hover` and `:focus` can be implemented with the events

-
-## How it works
-
-Every call to `StyleSheet.create` extracts the unique _declarations_ and
-converts them to a unique CSS rule. This is sometimes referred to as "atomic
-CSS". All the core components map their `style` property-value pairs to the
-corresponding `className`'s.
-
-By doing this, the total size of the generated CSS is determined by the
-total number of unique declarations (rather than the total number of rules in
-the application), making it viable to inline the style sheet when pre-rendering
-on the server. Styles are updated if new module bundle are loaded asynchronously.

-JavaScript definition:

-const styles = StyleSheet.create({

-  },
-  text: {
-    color: 'gray',

-  }
-})
-```
-
-CSS output:
-
-```css
-.__style1 { color: gray; }
-.__style2 { font-size: 2rem; }
-.__style3 { font-size: 1.25rem; }
