How are jetons used in a script task?

Hello everyone,

I wrote  a simple Powershell script to copy folders from one directory to another. I tested the script locally on my computer and it works fine.

Now I would like to copy a folder from one network drive to another. I noticed that in a script task, we can insert jetons.

I assume that jetons are like parameters and in my case, the two parameters that I would need would be server name (the network drives are actually two different servers)

Can someone please direct me to some documentations on how jetons are used in a script task particularly with Powershell?

thank you in advance
