So,if a i made a game that's 2 mb,then i wanted to put a read me into the zip file,does that count?

That's a good question.   A README with instructions, notes, attributions, etc. seems like a logical thing to include with the projects.  And since the REAMME isn't project data, it shouldn't count.  Let's do it - I'll add a README to the short list of items not included in the sizing.
