itch.io

Hi this is my first game ever.  I am simply trying to package the third person test scene to itch.

I package it up using Windows, and it is successful and gives me a folder called 'windows' with the game .exe file, two .txt files, and two other folders.  

How do I get this onto itch?  I need a zip with a index html inside of it to upload right?  Do I just manually zip up that whole 'windows' folder?  Where do I get this index html from?
