Where is the Worldpay Plugin?

I was able to find the documentation for Worldpay but that does not explain where to find it the Plugin and how to enable it. And no, it is not listed in the Joomla plugins after Hikashop is installed. I saw a link to Github but there is no plugin, just some loose files. I am an integrator, not a programmer. Honestly slowly but surly I loose patience with Hikashop.

Hello,

In github, you can click on the button "Clone or download" to get a "zip" of the repository.
Thanks to that zip you will be able to install the plugin.

Afterwards most of repos have "releases" but that's right that some, do not.

Regards,
