+# NativeBase ↔ gluestack
+
+> 🚀 NativeBase is evolving into gluestack-ui! What was planned as NativeBase v4 is now available as gluestack-ui - our next-generation component library built for better performance, enhanced customization, and improved developer experience. Visit [gluestack.io](http://gluestack.io) to get started!
+
+## Important Notice: Evolution to gluestack-ui
+
+NativeBase is entering maintenance mode as we evolve into gluestack-ui. This transition represents our commitment to providing the React Native community with more powerful, flexible, and performant UI components. If you are starting a new project with NativeBase, we recommend using [gluestack-ui](https://ui.gluestack.io/) instead. [Know More](https://nativebase.io/blogs/road-ahead-with-gluestack-ui).
