So I finished my first module, did all I have to do. Followed standards, and tried to upload the module to sell it on prestashop. However I'm stuck at: Invalid module key ! when I upload the .zip file.
I really don't know what went wrong, can someone share some insight with me please?

EDIT:
Found it. It actually was the first line in the upload which I needed to include. I'm not sure how I managed to miss something that obvious. -Sorry
