Deploying Existing SSRS Reports in Test

Hello,

I'm new to SSRS and I need to deploy reports that exist in Live to our Test environment as soon as possible. Unfortunately, my predecessors did not add any of the custom reports to Test.  There's nothing like trial by fire.  We're on RAMP.  The only instructions I've received from Tessitura are: 

1)  Go into the BIDS project containing your custom reports in LIVE
2)  Change the config to the TEST location and deploy

If someone could step me through this, I'd greatly appreciate it.

Thank you!
