-# react-native-timezone
+# React Native Timezone and Region
 
-A Simple react native module to get Timezone and Region of the Android/iOS device.
+[![Maintainability](https://api.codeclimate.com/v1/badges/3713253a365fe6a55615/maintainability)](https://codeclimate.com/github/samitha9125/react-native-timezone/maintainability)
 
-## Installation
+A Simple react native module to get Timezone and the Region of the Android/iOS devices.
 
-```sh
-npm install react-native-timezone
-```
+# Motivation
 
-## Usage
+For a project of mine, I had to acquire the current selected timezone of the user. But unfortunately I could not find any react native package or react native in-build function which facilitates this. Thus I created a small library.
+Also, in v3.0.0 and above, you can access the Region details. More details can be found below.
 
-```js
-import { multiply } from 'react-native-timezone';
+# Compatibility
 
-// ...
+Timezone version 3.0.0 only supports React Native version 0.62.3 and above due to React Native Regular Expression Denial of Service (ReDoS) vulnerability.
 
-const result = await multiply(3, 7);
-```
+| React native version | Tested | Result |
+| -------------------- | ------ | ------ |
+| 0.62.3 +             | ✅     | ✅     |
+| 0.70.0 +             | ✅     | ✅     |
+| 0.73.0 +             | ✅     | ✅     |
+
+# Installation
+
+`npm i react-native-timezone`
+
+## iOS
 
-## Contributing
+Do `cd ios/ && pod install`.
 
-See the [contributing guide](CONTRIBUTING.md) to learn how to contribute to the repository and the development workflow.
+# Usage
+
+```javascript
+import TimeZone from 'react-native-timezone';
+
+export default function App() {
+  React.useEffect(() => {
+    const timezone = Timezone.getTimeZone();
+    const isAutoTimeZoneEnabled = Timezone.isAutoTimeZoneEnabled();
+    const telephonyRegion = Timezone.getRegionByTelephony();
+    const localeRegion = Timezone.getRegionByLocale();
+    // Update state or use data as needed
+  }, []);
+
+  // Render your component
+}
+```
