+PyTorch’s edge specific library is [ExecuTorch](https://github.com/pytorch/executorch/) and is designed to be lightweight, very performant even on devices with constrained hardware such as mobile phones, embedded systems and microcontrollers.
+
+ExecuTorch relies heavily on PyTorch core technologies such as [torch.compile](https://pytorch.org/docs/stable/torch.compiler.html) and [torch.export](https://pytorch.org/docs/stable/export.html), and should be very familiar to anyone who has used PyTorch in the past.
+
+### Getting Started
+You can get started by following the [general getting started guide](https://pytorch.org/executorch/stable/getting-started.html#) or jump to the specific steps for your target device.

+* [Using ExecuTorch with C++](https://pytorch.org/executorch/stable/using-executorch-cpp.html)
+
+### Hardware Acceleration
+ExecuTorch provides out of the box hardware acceleration for a growing number of chip manufacturers. See the following resources to learn more about how to leverage them:
