 Please note that FastSAM only supports detection and segmentation of a single class of object. This means it will recognize and segment all objects as the same class. Therefore, when preparing the dataset, you need to convert all object category IDs to 0.
 
+### Track Usage
+
+To perform object tracking on an image, use the `track` method as shown below:
+
+!!! Example
+
+    === "Python"
+   
+        ```python
+        from ultralytics import FastSAM
+
+        # Create a FastSAM model
+        model = FastSAM('FastSAM-s.pt')  # or FastSAM-x.pt
+
+        # Track with a FastSAM model on a video
+        results = model.track(source="path/to/video.mp4", imgsz=640)
+        ```

+        ```bash
+        yolo segment track model=FastSAM-s.pt source="path/to/video/file.mp4" imgsz=640

 ## FastSAM official Usage
 
 FastSAM is also available directly from the [https://github.com/CASIA-IVA-Lab/FastSAM](https://github.com/CASIA-IVA-Lab/FastSAM) repository. Here is a brief overview of the typical steps you might take to use FastSAM:

 !!! Note
 
     The YOLO-World models provided by Ultralytics come pre-configured with [COCO dataset](../datasets/detect/coco.md) categories as part of their offline vocabulary, enhancing efficiency for immediate application. This integration allows the YOLOv8-World models to directly recognize and predict the 80 standard categories defined in the COCO dataset without requiring additional setup or customization.
