VDR Backend addon username and Password?

Is there some document that I am not seeing? Where is the VDR back-end username and password?

I wanted to test VDR but even on their site they make reference to "the documentation" but no links to it.

I was looking for "documentation" The "readme " is not provided when installing the back-end service.

BTW the "username and password" i refer to is to get into the back-end. That should be obvious

Thanks you despite the seemingly rude demeanor

<<<UPDATE >>>>>

That username and password seem to work till you click on a link and it just takes me back to login page
