Add Paper To BookPro dynamically

AddDynamicPages.cs

using UnityEngine;
using System.Collections;

public class AddDynamicPages : MonoBehaviour {

    public GameObject FrontPagePrefab;
    public GameObject BackPagePrefab;
    // Use this for initialization
    void Start () {
	
	}
	public void AddPaper(BookPro book)
    {
        GameObject frontPage = Instantiate(FrontPagePrefab);
        GameObject backPage = Instantiate(BackPagePrefab);
        frontPage.transform.SetParent(book.transform,false);
        backPage.transform.SetParent(book.transform, false);
        Paper newPaper = new Paper();
        newPaper.Front = frontPage;
        newPaper.Back = backPage;
        Paper[] papers = new Paper[book.papers.Length + 1];
        for(int i=0;i< book.papers.Length;i++)
        {
            papers[i] = book.papers[i];
        }
        papers[papers.Length-1] = newPaper;
        book.papers = papers;
        //update the flipping range to contain the new added paper
        book.EndFlippingPaper = book.papers.Length - 1;
        book.UpdatePages();
    }
	// Update is called once per frame
	void Update () {
	
	}
}

sir please explain how to use this script .....

1)-Create a new gameobject in the scene and attach the script on it
2)-Create a prefab for the front and back pages (should be similar to the the page object that is created by the editor and i.e. has the same components)
3)-Assign the front and back prefabs to this component
4)Call the function AddPaper when you want to add a new paper in the book
5)you may need to customize this function to add a paper in specific position in the book or to change some parts of the front and back prefabs dynamically
