 Once ExecuTorch is [set-up](https://pytorch.org/executorch/main/getting-started.html), exporting and running the model on device is a breeze.
 
 ExecuTorch's LLM export scripts require the checkpoint keys and parameters have certain names, which differ from those used in Hugging Face.
-So we first use a conversion script that converts the Hugging Face checkpoint key names to ones that ExecuTorch expects:
+So we first use a script that converts the Hugging Face checkpoint key names to ones that ExecuTorch expects:
+The following script does this for you.

-Once we have the checkpoint, we export it to ExecuTorch with the XNNPACK backend as follows.

 After that you can run the model in a mobile app (see [Running in a mobile app](#running-in-a-mobile-app)).

+(We try to keep these instructions up-to-date, but if you find they do not work, check out our [CI test in ExecuTorch](https://github.com/pytorch/executorch/blob/main/.ci/scripts/test_torchao_huggingface_checkpoints.sh) for the latest source of truth, and let us know we need to update our model card.)
