Very simply, what you need to do to get started is find the 'Rec' output from your mixer. From here you'll need to find / buy a 2 RCA Phono - 3.5mm Stereo Minijack Cable. The two phono sockets obviously connect into the back of your mixer, and the 3.5mm minijack into your computers line in socket - should be near your speaker output and microphone input. You may need to enable the line in via your sound card settings. After this, you're pretty much good to go other than acquiring some software to record.
