+## 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:** Selfie segmentation with `onnx-community/mediapipe_selfie_segmentation-web`.
+
+```js
+import { AutoModel, RawImage, Tensor } from '@huggingface/transformers';
+
+// Load model and processor
+const model_id = 'onnx-community/mediapipe_selfie_segmentation-web';
+const model = await AutoModel.from_pretrained(model_id, { dtype: 'fp32' });
+
+// Load image from URL
+const url = 'https://huggingface.co/datasets/Xenova/transformers.js-docs/resolve/main/selfie_segmentation.png';
+const image = await RawImage.read(url);
+
+// Predict alpha matte
+const { alphas } = await model({
+    pixel_values: new Tensor(
+        'uint8',
+        image.data,
+        [1, image.height, image.width, 3],
+    ),
+});
+
+// Save output mask
+const mask = RawImage.fromTensor(alphas[0].mul(255).to('uint8'), 'HWC')
+mask.save('mask.png');
+
+// (Optional) Apply mask to original image
+const result = image.clone().putAlpha(mask);
+result.save('result.png');
+```
+
+| Input image | Predicted mask | Output image |
