Link to 'download a zip of the project' links to page with no downloads

If you follow the link on:

https://github.com/clayton/jenkins-radiator.git

To:

https://github.com/clayton/jenkins-radiator/downloads

You get the message:

"There aren’t any uploads for this repository."

@clayton Any updates on this? I have a new project where I'd love to use your radiator!
