+## Model Logging
+`CmfRayLogger` can now log the model during trials. To enable this, the `train.report` method must include a special key: `"model_path"`. The value of `"model_path"` should be a relative path pointing to the saved model within the CMF directory.
+
+Important: Ensure that the `"model_path"` is relative, as the DVC wrapper expects all paths nested within the CMF directory to be relative.
+```Python
+train.report({
+    "accuracy": 0.95,
+    "loss": 0.05,
+    "model_path": "models/example_model.pth"
+})
+```

 ## Output
-During each trial, `CmfRayLogger` will automatically create a CMF object with attributes set as `pipeline_name`, `pipeline_stage`, and the CMF execution as `trial_id`. It captures the trial's output and logs it under the metric key `'Output'`.
