How To Switch Between Scenes

Hi, how can I switch between scenes?
Example: Menu Screen>Click on Play>Pop up with some text>Game
.Sorry for my bad English but I’m Italian

First, make sure that at the top, it says:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

Then, you can use this line of code to load a specific scene based on the scene’s index number:

SceneManager.LoadScene (sceneBuildIndex:/*Put the number here*/);

Or, you can use this script to load a scene based on the name of a scene:

SceneManager.LoadScene (sceneName:"Put the name of the scene here");

Simply use Scene Manager, e.g.:

SceneManager.LoadScene("MyScene");
