 https://huggingface.co/ibm-granite/granite-timeseries-patchtsmixer with ONNX weights to be compatible with Transformers.js.
 
+## Usage (Transformers.js)
+
+If you haven't already, you can install the [Transformers.js](https://huggingface.co/docs/transformers.js) JavaScript library from [NPM](https://www.npmjs.com/package/@huggingface/transformers) using:
+```bash
+npm i @huggingface/transformers
+```
+
+**Example:** Time series forecasting w/ `onnx-community/granite-timeseries-patchtsmixer`
+
+```js
+import { PatchTSMixerForPrediction, Tensor } from '@huggingface/transformers';
+
+const model_id = "onnx-community/granite-timeseries-patchtsmixer";
+const model = await PatchTSMixerForPrediction.from_pretrained(model_id, { dtype: "fp32" });
+
+const dims = [64, 512, 7];
+const prod = dims.reduce((a, b) => a * b, 1);
+const past_values = new Tensor('float32',
+    Float32Array.from({ length: prod }, (_, i) => i / prod),
+    dims,
+);
+const { prediction_outputs } = await model({ past_values });
+console.log(prediction_outputs);
+```

 Note: Having a separate repo for ONNX weights is intended to be a temporary solution until WebML gains more traction. If you would like to make your models web-ready, we recommend converting to ONNX using [🤗 Optimum](https://huggingface.co/docs/optimum/index) and structuring your repo like this one (with ONNX weights located in a subfolder named `onnx`).
