How do I upload my unity game to gamejolt?

I want to upload a small game to gamejolt. They want a .Zip file. I’ve tried several ways to make a zip file for my game and they weren’t accepted.

How do I make a proper zip file for my game?

There are lots of video tutorials for this and I’m sure it says how to on their page… You are supposed to try to find the answer before posting…
