 To use on platforms without pre-built binaries, you can build Node.js binding from source and consume it by `npm install <onnxruntime_repo_root>/js/node/`. See also [instructions](https://onnxruntime.ai/docs/build/inferencing.html#apis-and-language-bindings) for building ONNX Runtime Node.js binding locally.
 
 # GPU Support
 
-Right now, the Windows version supports only the DML provider. Linux x64 can use CUDA and TensorRT.
+Right now, the Windows version supports WebGPU execution provider and DML execution provider. Linux x64 can use CUDA and TensorRT.
 
 ## CUDA EP Installation
 
-To use CUDA EP, you need to install the CUDA EP binaries. By default, the CUDA EP binaries are installed automatically when you install the package. If you want to skip the installation, you can pass the `--onnxruntime-node-install-cuda=skip` flag to the installation command.
