 You’ll be able to use the models through our API as well. The API is coming soon and will have some exciting features. Stay tuned!
 
+### 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/@xenova/transformers) using:
+```bash
+npm i @xenova/transformers
+```
+
+You can then use the model to compute embeddings as follows:
+
+```js
+import { pipeline, cos_sim } from '@xenova/transformers';
+
+// Create a feature-extraction pipeline
+const extractor = await pipeline('feature-extraction', 'mixedbread-ai/mxbai-embed-2d-large-v1', {
+    quantized: false, // (Optional) remove this line to use the 8-bit quantized model
+});
+
+// Compute sentence embeddings (with `cls` pooling)
+const sentences = ['Who is german and likes bread?', 'Everybody in Germany.' ];
+const output = await extractor(sentences, { pooling: 'cls' });
+
+// Set embedding size and truncate embeddings
+const new_embedding_size = 768;
+const truncated = output.slice(null, [0, new_embedding_size]);
+
+// Compute cosine similarity
+console.log(cos_sim(truncated[0].data, truncated[1].data)); // 0.6979532021425204
+```
