It's another story, but I think this is a good point for people starting in Powershell just to keep in mind as they do more unguided work that requires looking for solutions online. Many articles, forum answers, and scripts floating around are presented to the reader as if there's a standard set of modules that everyone is using and it's just not the case. It's also something that you may just get dumped into - my current job heavily relies on a web of obscure modules with little to no documentation that has required a lot of digging and working backward for me to understand.
