Once you have ready to script with PowerShell (PS) you need to know some basic knowledge, commenting is one of these.

Commenting is useful to indicate the features of the script, or maybe comment something interesting about the code.

For commenting you have two options:

— Using # (hash character):

# This is a comment
[your code]

— Using multi-line comment :

<#
This is a
multi-line
comment
#>
[your code]
