The standard way to stream a single application using Rainway is to run it on the Windows desktop, and use App Isolation to hide the rest of the desktop from the viewer.
Rainway also allows a Full Desktop stream, in which no single app is isolated and the entire desktop is streamed as-is. When accepting a stream request (see "Streaming" in your language of choice's SDK tutorial), set the stream type to StreamType.FullDesktop to enable this.
If you have multiple monitors, the "primary" monitor is streamed. Check your Display settings in Windows (Start → Settings → System → Display) to see which one this is.
