currently the only legal way to get it on steam is to buy a sealed PC copy of Rocksmith 2014 or Rocksmith 2014 Remastered.  Each sealed box has a steam code in it that can be redeemed.  The key point being, be aware of scams or people selling you items without the steam code inside.  

There are other non legal ways to get Rocksmith but we will not be discussing them here.  
Do what you will, just don't tell us about it.
