Main Files in upload

I want to upload my theme on themeforest. but i am confused about “Main files” and “ThemeForest Files Included” boxes in uploader. Please guide me so i can upload my theme. Thanks

In the “ThemeForest Files Included” box you should choose a few types of your files (example: HTML, CSS, JS Files).
In the “Main files” you should upload main files of your item, which a buyer will get after purchase.
Good luck!

Should i include wordpress theme files in main zip file along with some read me type files.
