Need little help regarding formating text for Fine Tuning

Hi to all.

I am trying to train my model with some of my old blog posts, but I dont have it clear about the text formating.

Normaly the text is shown with spaces and empty lines in the text. But every example I saw on the internet the responce text is continous - aaaa, dddd, ggggg, ttttt, -aaaa -bbbbb…

Is this the only way? As I want to get responce with similar structure like I write.
Or there is another option?

Thank you
