+### Supported Labels
+
+```
+['NORMAL', 'PNEUMONIA']
+```
+
+### How to use
+
+- Install [ultralyticsplus](https://github.com/fcakyon/ultralyticsplus):
+
+```bash
+pip install ultralyticsplus==0.0.23 ultralytics==8.0.21
+```
+
+- Load model and perform prediction:
+
+```python
+from ultralyticsplus import YOLO, postprocess_classify_output
+
+# load model
+model = YOLO('keremberke/yolov8n-chest-xray-classification')
+
+# set model parameters
+model.overrides['conf'] = 0.25  # model confidence threshold
+
+# set image
+image = 'https://github.com/ultralytics/yolov5/raw/master/data/images/zidane.jpg'
+
+# perform inference
+results = model.predict(image)
+
+# observe results
+print(results[0].probs) # [0.1, 0.2, 0.3, 0.4]
+processed_result = postprocess_classify_output(model, result=results[0])
+print(processed_result) # {"cat": 0.4, "dog": 0.6}
+```
