+# Ericsson Day Demo Sentiment Model
+
+This model is based on **DistilBERT fine-tuned on SST-2** for sentiment analysis.  
+It has been wrapped with a custom `model.py` that also reports the internal processing time.
+
+## Model description
+- **Task**: Sentiment classification (positive/negative)
+- **Base model**: `distilbert-base-uncased-finetuned-sst-2-english`
+- **Wrapper**: Custom `model.py` that returns `"processing_time_sec"`
+
+## Example usage
+
+```python
+from transformers import pipeline
+classifier = pipeline("sentiment-analysis", model="ED-Demo/Ericsson_day_demo_model")
+print(classifier("I love Hugging Face!"))
