<!-- Description of your issue -->

Hello I'm trying to use BART summarization model. I have a dataset that take the form of dataframe which has two columns 'document' and 'summary'. 

Q1.
I read this Readme.md.
> line.this should make a directory called cnn_dm/ with files like test.source. To use your own data, copy that files format. Each article to be summarized is on its own 

I don't understand this sentences well. So I just saw the cnn datasets(train.source, train.target, test.source, test.target). **How can i distinguish between each documents?**

Q2. 
**How can i change my own datasets into the cnn files format?**
