+## React Native New Architecture Support
+
+ViroReact now supports React Native's New Architecture (Fabric) with automatic detection. The library will automatically detect whether your app is using the New Architecture and use the appropriate implementation:
+
+```javascript
+// Import ViroReact components - they will automatically use the right implementation
+import { ViroARScene, Viro3DObject } from "@reactvision/react-viro";
+```
+
+If you prefer to explicitly use a specific implementation, you can still do so:
+
+```javascript
+// Explicitly use the Legacy Architecture implementation
+import { ViroARScene, Viro3DObject } from "@reactvision/react-viro/index";
+
+// Explicitly use the New Architecture (Fabric) implementation
+import { ViroARScene, Viro3DObject } from "@reactvision/react-viro/fabric";
+```
+
+The API remains the same across all implementations, but the New Architecture version provides better performance and compatibility with future React Native versions.
+
+> **Note:** The Legacy Architecture support is deprecated and will be removed in version 3.0.0. We recommend enabling the New Architecture in your app for better performance and future compatibility.
+
+For more detailed information about the New Architecture support, including API compatibility and known limitations, see the [NEW_ARCHITECTURE.md](./NEW_ARCHITECTURE.md) document.

 # Examples
 
-See our [Example projects](https://viro-community.readme.io/docs/examples) page. These are a little old (~2019) but are a great reference point for how to use bits of the library.

 ViroReact was originally developed by the [Viro Media](http://www.viromedia.com/), but was open-sourced in 2019. In late 2020, the Viro Community was formed to help maintain and move the project onwards, updating it so it could run with modern versions of React Native, and start to add in new features.
 
-Following years of support, in 2025, [Morrow acquired ReactVision](https://www.themorrow.digital/blog/morrow-acquires-reactvision-and-viroreact-library) to help accelerate its development and give it the resources needed to enable ReactVision to capture the rapidly growing demand for ViroReact. ReactVision now has a team working full-time to help ensure the codebase is updated and ready for the future of XR / Spatial Computing. Our vision is to enable React Native developers to build AR and VR applications that can run across all XR devices (smartphones, smart glasses, and headsets) off of a single React Native codebase.

 We, as a community, owe a great debt to Viro Media and the people who developed this library originally. We hope to make them proud as it continues to develop and grow within ReactVision.
