Cannot find any documentation on Coronium SkyTable

All the links related to the plugin "Coronium SkyTable "are gone or at lest I keep getting

404 :

I know the plugin can be purchased here https://marketplace.coronalabs.com/corona-plugins/coronium-skytable but I want to see how it works before paying for it.

Can someone tell me where I can find documentation for this plugin?

This is obvious, but if the official documentation is down, then I’d recommend reaching out to the plugin’s author.
