How to add log to this script?

All,

I am new to Powershell so please be kind.  I am creating a script that will call a .txt file with a list of specific pcs and then install a registry key on them.  I have this part working.  What I would like, is for it to output some kind of log to confirm which pcs received the reg keys and which didnt.  Is this possible?  

Thanks in advance,

Dustin

Get-Content C:\pcs.txt
Start-Process reg -Argumentlist "import C:\Nautilus.reg"
