C# Saving data to the player's computer

I am currently developing a racing game. I have just set up a script to give my players money when they finish first, second or third in a race and to count how much money they have, and display it on screen. I have been trying to find out how to save the amount of money a player has when they quite, and load it back up when they join again.

My Money Script

 using UnityEngine;
 using System.Collections;
 
 public class CoinsAndShop : MonoBehaviour {
 
 //Variables Start
 public int money = 0;
     public TextMesh guiMoney;
 //Used to give money to the player when come first, second or third in a race
 
 public bool raceFirst;
 public bool raceSecond;
 public bool raceThird;
 
 
 //Variables End
     //Displays Money
     void Start(){
         guiMoney.text = "Money : 0";
     }
 
 
     //Basic money script
 
 void Update(){  //Updates once per frame
 
    if (raceFirst == true) { 
     money += 1500;
         raceFirst = false; 
                 }
    if (raceSecond == true) {
     money += 1000;
     raceSecond = false;
                 }
    if (raceThird == true) { 
     money += 500;
     raceThird = false;
                 }
                 
 
         }

I am very new to coding and game making, so any help is much appreciated. Thanks in advance for your help!
