Windows Admin Center 2410: Missing documentation

The Windows Admin Center 2410 (mg) has a completely different setup procedure, new cmdlets etc. But I am missing the documentation. Especially I want WindowsAuthentication getting to work. When I change the mode, the service crashes all the time. The best documentation, I could find was this blog entry: Windows Admin Center installation – old vs new | Going down the IT rabbit hole

But I cannot believe, Microsoft is releasing a product without and docs.
