What files do I upload?

I've finished my game but now I'm not sure what to do after exporting the completed game. I tried both the HTML5 and Kongregate options and it looks like the output files/folder are exactly the same (see attachment).

But when I go to Kongregate, it asks for one file and expects it to be in html format, so is that "index.html"? What else should I upload? Kongregate only seems to let me upload one other file but there are files & folders in the export directory.

If this is explained elsewhere or someone has an easy to follow method, that would be great!

Doing a search for Kongregate in the tutorials brings up this as the first hit:

I've got a bit of egg on the face. I did a search on the tutorials for "publish to kongregate" but I should have gone simpler! I appreciate you pointing out the obvious, seriously.

I tried the link above from NateB but didn't have much luck. I did find this other tutorial which helped me get it on Kongregate with minimal fuss:
