-🚧 Page under construction.
+With Supervision, you can easily [annotate](https://supervision.roboflow.com/annotators/) predictions obtained from a variety of object detection and segmentation models. This document outlines how to run inference using the [Ultralytics](https://github.com/ultralytics/ultralytics) YOLOv8 model, load these predictions into Supervision, and annotate the image.
+
+## Run Inference
+
+First, you'll need to obtain predictions from your object detection or segmentation model.
+```python
+import cv2
+from ultralytics import YOLO
+
+model = YOLO("yolov8n.pt")
+image = cv2.imread("image.jpg")
+results = model(image)[0]
+```
+
+## Load Predictions into Supervision
+
+Now that we have predictions from a model, we can load them into Supervision. We can do so using the [`sv.Detections.from_ultralytics`](https://supervision.roboflow.com/detection/core/#supervision.detection.core.Detections.from_ultralytics) method, which accepts model results from both detection and segmentation models.
+
+```python
+import cv2
+from ultralytics import YOLO
+import supervision as sv
+
+model = YOLO("yolov8n.pt")
+image = cv2.imread("image.jpg")
+results = model(image)[0]
+detections = sv.Detections.from_ultralytics(results)
+```
+
+You can conveniently load predictions from other computer vision frameworks and libraries using:

+
+
+## Annotate Image
+
+Finally, we can annotate the image with the predictions. Since we are working with an object detection model, we will use the [`sv.BoundingBoxAnnotator`](https://supervision.roboflow.com/annotators/#supervision.annotators.core.BoundingBoxAnnotator) and [`sv.LabelAnnotator`](https://supervision.roboflow.com/annotators/#supervision.annotators.core.LabelAnnotator) classes. If you are running the segmentation model [`sv.MaskAnnotator`](https://supervision.roboflow.com/annotators/#supervision.annotators.core.MaskAnnotator) is a drop-in replacement for [`sv.BoundingBoxAnnotator`](https://supervision.roboflow.com/annotators/#supervision.annotators.core.BoundingBoxAnnotator) that will allow you to draw masks instead of boxes.
+
+```python
+import cv2
+from ultralytics import YOLO
+import supervision as sv
+
+model = YOLO("yolov8n.pt")
+image = cv2.imread("image.jpg")
+results = model(image)[0]
+detections = sv.Detections.from_ultralytics(results)
+
+bounding_box_annotator = sv.BoundingBoxAnnotator()
+label_annotator = sv.LabelAnnotator()
+
+labels = [
+    results.names[class_id]
+    for class_id
+    in detections.class_id
+]
+
+annotated_image = bounding_box_annotator.annotate(
+    scene=image, detections=detections)
+annotated_image = label_annotator.annotate(
+    scene=annotated_image, detections=detections, labels=labels)
+```
+
+![Predictions plotted on an image](https://media.roboflow.com/supervision_annotate_example.png)
+
+## Display Annotated Image
+
+To display the annotated image in Jupyter Notebook or Google Colab, use the [`sv.plot_image`](https://supervision.roboflow.com/utils/notebook/#supervision.utils.notebook.plot_image) function.
+
+```python
+sv.plot_image(annotated_image)
+```

+## Guidelines for Contributing
+
+We welcome contributions from the community in the form of examples, applications, and
+guides. To contribute, please follow these steps:
+
+1. Create a pull request (PR) with the `[Example]` prefix in the title, adding your
+project folder to the `examples/` directory in the repository.
+2. Confirm your project aligns with the following standards:
+   - Incorporates the `supervision` package.
+   - Provides a `README.md` file, detailing the instructions to execute the project.
+   - Showcases visual results, demonstrating the app's functionality.
+   - Avoids adding large assets or dependencies unless absolutely necessary.
+   - The contributor is expected to provide support for issues related to their
+examples.
+   - In case the presented model has licensing complications, kindly specify them to
+circumvent potential misunderstandings.
+
+For inquiries or concerns about these prerequisites, feel free to raise a PR. We are
+committed to assist and guide you.
