-# Introduction
-
-This repository hosts the semantic segmentation
-[LRASPP](https://docs.pytorch.org/vision/main/models/lraspp.html) models
-for the [React Native
-ExecuTorch](https://www.npmjs.com/package/react-native-executorch) library. It
-includes models 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 these 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. 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 **ExecuTorch** version 1.1.0 and no forward
-compatibility is guaranteed. Older versions of the runtime may not work with
-these files.
+# lraspp
+
+This repository hosts the **lraspp** models exported for the
+[React Native ExecuTorch](https://www.npmjs.com/package/react-native-executorch)
+library as ExecuTorch `.pte` programs, ready to run on device.

+## Variants
+
+| Path | Backend | Precision |
+| --- | --- | --- |
+| `coreml/lraspp_mobilenet_v3_large_coreml_fp16.pte` | coreml | fp16 |

+
+## Unshipped backends
+
+A backend directory carrying a `NOTES.md` and no `.pte` was exported and
+not published. Its note records what went wrong.

+
+## Compatibility
+
+These files are published for the **ExecuTorch v1.4.1** runtime. ExecuTorch
+gives no forward compatibility guarantee, so an older runtime may fail to load
+them.
+
+To use them in React Native ExecuTorch, pass the model constant shipped in the
+library's model registry to the corresponding task pipeline. See the
+[documentation](https://docs.swmansion.com/react-native-executorch/docs/fundamentals/loading-models).
+
+To load these files in your own ExecuTorch runtime, read the
+[compatibility note](https://github.com/pytorch/executorch/blob/main/runtime/COMPATIBILITY.md)
+first.
