How I manage my own domain knowledge articles?

[Southpika]

I want to know the format of my documents if I want to fine-tune a model on my domain knowledge. If my documents are many complete articles should I split them into many small questions : : questions from articles :answers from articles

or can I feed the model with original article(how can I feed the model with my whole article?).

many thanks!
