To add a Collider to a GameObject in Unity, follow these steps:
1. Select the GameObject in the Scene View or Hierarchy window.
2. In the Inspector window, select the Add Component button.
3. Type "Collider" in the search box and you will get various collider options such as Box Collider, Sphere Collider, Capsule Collider, etc.
4. Select the type of Collider you want to add to your GameObject.
5. The Collider component will be added to your GameObject.
Alternatively, you can also add a Collider component by right-clicking on the GameObject in the Hierarchy window and selecting "Add Component" -> "Physics" -> the type of collider you need.
