+Object tracking is a task that involves identifying the location and class of objects, then assigning a unique ID to
+that detection in video streams.
+
+The output of tracker is the same as detection with an added object ID.
+
+## Available Trackers
+
+The following tracking algorithms have been implemented and can be enabled by passing `tracker=tracker_type.yaml`
+
+* [BoT-SORT](https://github.com/NirAharon/BoT-SORT) - `botsort.yaml`
+* [ByteTrack](https://github.com/ifzhang/ByteTrack) - `bytetrack.yaml`
+
+The default tracker is BoT-SORT.
+
+## Tracking
+
+Use a trained YOLOv8n/YOLOv8n-seg model to run tracker on video streams.
+
+!!! example ""
+
+    === "Python"
+    
+        ```python
+        from ultralytics import YOLO
+        
+        # Load a model
+        model = YOLO("yolov8n.pt")  # load an official detection model
+        model = YOLO("yolov8n-seg.pt")  # load an official segmentation model
+        model = YOLO("path/to/best.pt")  # load a custom model
+        
+        # Track with the model
+        results = model.track(source="https://youtu.be/Zgi9g1ksQHc", show=True) 
+        results = model.track(source="https://youtu.be/Zgi9g1ksQHc", show=True, tracker="bytetrack.yaml") 
+        ```
+    === "CLI"
+    
+        ```bash
+        yolo track model=yolov8n.pt source="https://youtu.be/Zgi9g1ksQHc"  # official detection model
+        yolo track model=yolov8n-seg.pt source=...   # official segmentation model
+        yolo track model=path/to/best.pt source=...  # custom model
+        yolo track model=path/to/best.pt  tracker="bytetrack.yaml" # bytetrack tracker
+
+        ```
+
+As in the above usage, we support both the detection and segmentation models for tracking and the only thing you need to do is loading the corresponding(detection or segmentation) model.
+
+## Configuration
+### Tracking
+Tracking shares the configuration with predict, i.e `conf`, `iou`, `show`. More configurations please refer to [predict page](https://docs.ultralytics.com/cfg/#prediction).
+!!! example ""
+
+    === "Python"
+    
+        ```python
+        from ultralytics import YOLO
+        
+        model = YOLO("yolov8n.pt")
+        results = model.track(source="https://youtu.be/Zgi9g1ksQHc", conf=0.3, iou=0.5, show=True) 
+        ```
+    === "CLI"
+    
+        ```bash
+        yolo track model=yolov8n.pt source="https://youtu.be/Zgi9g1ksQHc" conf=0.3, iou=0.5 show
+
+        ```
+
+### Tracker
+We also support using a modified tracker config file, just copy a config file i.e `custom_tracker.yaml` from [ultralytics/tracker/cfg](https://github.com/ultralytics/ultralytics/tree/main/ultralytics/tracker/cfg) and modify any configurations(expect the `tracker_type`) you need to.
+!!! example ""
+
+    === "Python"
+    
+        ```python
+        from ultralytics import YOLO
+        
+        model = YOLO("yolov8n.pt")
+        results = model.track(source="https://youtu.be/Zgi9g1ksQHc", tracker='custom_tracker.yaml') 
+        ```
+    === "CLI"
+    
+        ```bash
+        yolo track model=yolov8n.pt source="https://youtu.be/Zgi9g1ksQHc" tracker='custom_tracker.yaml'
+
+        ```
+Please refer to [ultralytics/tracker/cfg](https://github.com/ultralytics/ultralytics/tree/main/ultralytics/tracker/cfg) page.
