Recording guitar in Cubase

Hello everyone, I’m new to the audio recording world and would like to get started on recording my guitar tracks. However when I’ve plugged my guitar into my focusrite and selected audio track. I cannot get a signal on Cubase, yet the guitar is playing through my monitors. I was wondering if there is any advice anyone can give me about setting up my inputs and outputs so that Cubase can pickup my guitar and not through the computer.

I am using a focusrite Scarlett 2i2

Thank you


I would recommend to watch Cubase Quick Start videos (for Cubase 7) on the official Steinberg YouTube channel.
