Camera distance from player [newbie[

I followed a tutorial to get this camera script, but its quite far from the player and i cant work out what part to change to make it closer.

using UnityEngine;
using System.Collections;

public class CameraController : MonoBehaviour 
{
	public GameObject player;
	private Vector3 offset;
	// Use this for initialization
	void Start () 
	{
		offset = transform.position;
	}
	
	// Update is called once per frame
	void LateUpdate () 
	{
		transform.position = player.transform.position + offset;
	}
}

The way it’s written, you should just be able to move the camera to wherever you want it to be in the editor and it should maintain that distance, but the player might need to be at 0,0,0.

Thank you, it was because my player wasn’t at 0,0,0
