-# Where is the template?
-The React Native Template has moved from being shipping inside the [react-native](https://www.npmjs.com/package/react-native) package to it's own package: [@react-native-community/template](https://github.com/react-native-community/template).
+<h1 align="center">

+    React Native visionOS
+  </a>
+</h1>
 
-## Why has it moved?
-The [React Native Frameworks RFC0759](https://github.com/react-native-community/discussions-and-proposals/blob/main/proposals/0759-react-native-frameworks.md#evolving-the-react-native-community-template--cli) provides background information.

+  <strong>Learn once, write anywhere:</strong><br>
+  Build spatial apps with React.
+</p>
 
-## When was it moved?
-The 0.75 release.
+React Native visionOS allows you to write visionOS with full support for platform SDK. This is a full fork of the main repository with changes needed to support visionOS.

+
+## 🎉 Building your first spatial React Native app
+Follow the [Getting Started](https://callstack.github.io/react-native-visionos-docs/category/getting-started) guide. If you wish to get started quickly, you can utilize this command: 
+
+```sh
+npx @callstack/react-native-visionos@latest init YourApp
+``` 
+
+
+## 📖 Documentation
+
+The full documentation for React Native visionOS can be found on our [website](https://callstack.github.io/react-native-visionos-docs).
+
+The source for the React Native visionOS documentation and website is hosted on a separate repo, @callstack/react-native-visionos-docs.
+
+## Contributing
+
+Prerequisites: 
+- Download the latest Xcode (at least 15.2)
+- Install the latest version of CMake (at least v3.29.0)
+
+Check out `rn-tester` [README.md](./packages/rn-tester/README.md) to build React Native from the source.
+
+Remember to use `RNTester-visionOS` target
+
+If `RNTester-visionOS` scheme is not showing up, click "New Scheme", which should be pre-populated with `RNTester-visionOS`. Build the app using Xcode.
+
+## Release process
+
+We use a script called `oot-release.js` which automatically releases `visionos` packages and aligns versions of dependencies with React Native core.
+
+Usage:
+
+```sh
+node ./scripts/oot-release.js --new-version "<visionos-version>" --react-native-version "<react-native-version>" --one-time-password "<otp>"
+```
+
+To test releases and template we use [Verdaccio](https://verdaccio.org/).
