The video tutorial introduces Unity components, explaining their purpose and how to create custom components using C# scripts. It covers the MonoBehaviour class, detailing its default functions like Start, Update, and Awake. The tutorial also discusses lifecycle events such as OnEnable and OnDisable, and how to expose fields to the Unity editor. Finally, it explains managing script execution order to ensure specific initialization sequences.
