Make camera move down steadily in a 2D game

Unity Engine
1

I want to make a level where the camera moves down at a set speed, almost like one of those scrolling super mario stages where you are racing against the camera. I can only find tutorials on how to make the camera follow the player.
Could someone help out and explain how to script it and why?

You can make any object move downwards by just moving its transform each frame.

Put this line in its update:

transform.position += Vector3.down * 10 * Time.deltaTime;

10 is the speed in units / second

Thank you! That solved it!
