 differ in the type of output they produce and the specific problem they are designed to solve.

 #### Modes
 
 YOLO models can be used in different modes depending on the specific problem you are trying to solve. These modes
-include train, val, and predict.
+include:
 
-- **Train**: The train mode is used to train the model on a dataset. This mode is typically used during the development
+**Train**: For training a YOLOv8 model on a custom dataset.  
-  and
+**Val**: For validating a YOLOv8 model after it has been trained.  
-  testing phase of a model.
+**Predict**: For making predictions using a trained YOLOv8 model on new images or videos.  
-- **Val**: The val mode is used to evaluate the model's performance on a validation dataset. This mode is typically used
+**Export**: For exporting a YOLOv8 model to a format that can be used for deployment.  
-  to
+**Track**: For tracking objects in real-time using a YOLOv8 model.  
-  tune the model's hyperparameters and detect overfitting.
+**Benchmark**: For benchmarking YOLOv8 exports (ONNX, TensorRT, etc.) speed and accuracy.
-- **Predict**: The predict mode is used to make predictions with the model on new data. This mode is typically used in
-  production or when deploying the model to users.
