+# Introduction
+
+This repository hosts the efficientnet_v2_s models for the [React Native ExecuTorch](https://www.npmjs.com/package/react-native-executorch) library. It includes model exported for xnnpack, as well as coreml in `.pte` format, ready for use in the **ExecuTorch** runtime.
+
+If you'd like to run these models in your own ExecuTorch runtime, refer to the [official documentation](https://pytorch.org/executorch/stable/index.html) for setup instructions.
+
+## Compatibility
+
+If you intend to use this models outside of React Native ExecuTorch, make sure your runtime is compatible with the **ExecuTorch** version used to export the `.pte` files. For more details, see the compatibility note in the [ExecuTorch GitHub repository](https://github.com/pytorch/executorch/blob/11d1742fdeddcf05bc30a6cfac321d2a2e3b6768/runtime/COMPATIBILITY.md?plain=1#L4). If you work with React Native ExecuTorch, the constants from the library will guarantee compatibility with runtime used behind the scenes.
+
+These models were exported using commit `fe20be98c` and **no forward compatibility** is guaranteed. Older versions of the runtime may not work with these files.
+
+### Repository Structure
+
+The repository is organized into two main directories:
+
+- `xnnpack`
+- `coreml`
+
+Each directory contains differentely exported version of the model.
+
+- The `.pte` file should be passed to the `modelSource` parameter.
