How do I make a credits button?

I want to have a credits button on my main menu that takes you on a click from my main menu scene to my credits scene. What is the code for that?

I need the code in C#.

It depends what you using for displaying your menu (UI, GUI, etc…) ?

Application.LoadLevel("Credits");

UI :

using UnityEngine;
  
  public class Load_Credits : MonoBehaviour {
  
      public void CreditsScene() {
          Application.LoadLevel(2);
      }
  }
