+This is an extractive text summarizer model trained on cnn_dailymail dataset. The trained model was saved as a joblib file, which can be used
+to load the models in your python script and perform text summarization tasks.
+This model is to be used in conjunction with the extract_features.py module. This module has a function that extracts the features and feed
+them to the saved model in the required format.
+
+To summarize text, follow these steps:
+from extract_features import extract_features
+features = extract_features(Article_you_want_to_summarize)
+summarized_sentences = model.predict(features)
+
+The summarized_sentences is a list of sentences of your summary.
