+
+#### How to use
+
+```python
+from transformers.pipelines import pipeline, AutoModelForQuestionAnswering, AutoTokenizer
+model = AutoModelForQuestionAnswering.from_pretrained(model_name)
+tokenizer = AutoTokenizer.from_pretrained("kuppuluri/telugu_bertu_tydiqa",
+                                          clean_text=False,

+                                          wordpieces_prefix='##')
+nlp = pipeline('question-answering', model=model, tokenizer=tokenizer)
+result = nlp({'question': question, 'context': context})
+```
+
+## Training data
