Azure and Powershell docs leave a lot to be desired. A lot of the time parameters are vaguely documented, return values completely undocumented. You have to inspect the object returned by a lot of things to get to understand what members and methods it has, and what they mean.
Examples illustrating what formats it expects inputs in? Forget it.
In contrast, Win32 which has been around for over 25 years is mostly stable now.
More than once, the "solution" to my problem was a blog post by a SharePoint consultant from India describing some undocumented flag to pass to some obscure command, "but of course, you should never do this on a production system". (I bear no ill will towards Indian SharePoint consultants, to be clear. I just find it really creepy they seem to enjoy this kind of torment.)
Just get-help -full/get-member everything or export-clixml it. But maybe I've done it for too long, so I don't see the weaknesses anymore.
