Key Moments - 2 Insights

Why do we need to run Install-Module before using a module?

Because the module is not on your computer until you download and install it from the PowerShell Gallery, as shown in steps 1 to 3 in the execution table.

What does Get-Module -ListAvailable do after installation?

It checks if the module is installed and available to use, confirming the installation as shown in step 4.
