+
+**React Native Progress WebView** is a wrapper of [React Native WebView](https://github.com/react-native-community/react-native-webview) to provide the loading status.
+
+## Platforms Supported
+
+- [x] iOS (both UIWebView and WKWebView)
+- [x] Android
+
+## Getting Started
+
+Read our [Getting Started Guide](https://github.com/react-native-community/react-native-webview) on React Native WebView page to configure the webview component.
+
+## Usage
+
+Import the `WebView` component from `react-native-webview` and use it like so:
+
+```jsx
+import React, { Component } from 'react';
+import { StyleSheet, Text, View } from 'react-native';
+import ProgressWebView from "react-native-progess-webview";
+
+// ...
+class App extends Component {
+  render() {
+    return (
+      <ProgressWebView source={{ uri: 'https://facebook.github.io/react-native/' }} />
+    );
+  }
+}
+```
+
+## API
+
+**React Native Progress Webview** supports all React Native Webview props. Read the [API Reference](https://github.com/react-native-community/react-native-webview/blob/master/docs/Reference.md) to explore. There are a couple of exclusive props related to the loading bar.
