 **React Native WebView** is a modern, well-supported, and cross-platform WebView for React Native. It is intended to be a replacement for the built-in WebView (which will be [removed from core](https://github.com/react-native-community/discussions-and-proposals/pull/3)).
 
-> We just swapped out the React Native WebView in our app with the version from React Native Community. The swap took less than a day, required almost no code modifications, and is faster and CSS works better. Props to everyone in the community (including those at Infinite Red) that helped get that component split out.

-## Migrate from React Native core WebView to React Native WebView
-
-Simply install React Native WebView and then use it in place of the core WebView. Their APIs are currently identical, except that this package defaults `useWebKit={true}` unlike the built-in WebView.
-
-## Troubleshooting
+## Common issues
 
 - If you're getting `Invariant Violation: Native component for "RNCWKWebView does not exist"` it likely means you forgot to run `react-native link` or there was some error with the linking process
 - There's a [problem](https://stackoverflow.com/questions/52872045/rendering-webview-on-android-device-overlaps-previous-siblings-from-same-parent) on some Android devices where the webview could overlap previous siblings from same parent. To fix this, wrap the WebView in a View with style `overflow: hidden`.
