In the previous tip we introduced the PowerShell Gallery and showed how to download content (scripts and modules).
Since the PowerShell Gallery is a public repository, and anyone can upload code, you should execise caution. Use Install-Module or Install-Script only if you know the author. Else, use Save-Module and Save-Script instead, and save the code to a neutral location for inspection. This way, you can review the code first without risking to accidentally invoke it.
