+## Model description
+​
+BartForConditionalGenerationModel for extreme summarization- creates a one line abstractive summary of a given article
+​
+## How to use
+​
+PyTorch model available
+​
+```python
+from transformers import AutoTokenizer, AutoModelWithLMHead, pipeline
+​
+tokenizer = AutoTokenizer.from_pretrained("yuvraj/xSumm")			
+model = AutoModelWithLMHead.from_pretrained("yuvraj/xSumm")
+​
+xsumm = pipeline('summarization', model=model, tokenizer=tokenizer)
+xsumm("<text to be summarized>")
+​
+## Limitations and bias
+Trained on a small fraction of the xsumm training dataset
