How do I add a score system?

Here's the Enemy Health -

 using System.Collections;
 using UnityEngine;
 
 public class EnemyHealthManager : MonoBehaviour {
 
     public int MaxHealth;
     public int CurrentHealth;
     public int scoreValue = 10;
 
     // Use this for initialization
     void Start()
     {
         CurrentHealth = MaxHealth;
     }
 
     // Update is called once per frame
     void Update()
     {
         if (CurrentHealth <= 0)
         {
             Destroy(gameObject);
         }
     }
 
     public void HurtEnemy(int damageToGive)
     {
         CurrentHealth -= damageToGive;
     }
 
     public void SetMaxHealth()
     {
         CurrentHealth = MaxHealth;
     }
 
     public void Scoring()
     {
         ScoreManager.score += scoreValue;
     }
 }

Here's the ScoreManger - using UnityEngine; using UnityEngine.UI; using System.Collections;

 public class ScoreManager : MonoBehaviour
 {
     public static int score;
 
 
     Text text;
 
     void Awake()
     {
         text = GetComponent<Text>();
         score = 0;
     }
 
 
     void Update()
     {
         text.text = "Score: " + score;
     }
 }
