+# Introduction
+
+This repository hosts the [BlazeFace](https://github.com/hollance/BlazeFace-PyTorch) models for the [React Native ExecuTorch](https://www.npmjs.com/package/react-native-executorch) library. 
+It includes the model exported for xnnpack 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 shipped with the library
+will guarantee compatibility with runtime used behind the scenes.
+
+These models were exported using **ExecuTorch** version 1.2.0 and **no forward
+compatibility** is guaranteed. Older versions of the runtime may not work with
+these files.
