Write a script file

Save as hello.ps1.

param(
  [string]$Name = "world"
)
Write-Output "Hello, $Name"

Use a path. From the current folder on Windows PowerShell:

.\hello.ps1 -Name Ada

Dot-source loads functions into your current session.

. .\tools.ps1

Add a help block so Get-Help .\hello.ps1 works for your own scripts.
