Yes, you need to build up a "Scene" using "Sources".

Sources can be webcams, capture devices and portions of your Windows screen (which come in the form of "Window Capture", "Display/Monitor Capture" and "Game Capture"). You can also add various audio sources. These can be audio inputs (like a microphone) or audio outputs (what a game or another program sends to your soundcard).
