Does anyone know how to use code to make a text box start a new line

C#

I am currently using a string array to feed different descriptions (in order) into a text box in unity.

The format is

string[] descriptionSheet = { "Whatever I put in here", "Other stuff in there"};

Some of these descriptions are multi parted and I would like to separate them visually once pasted into the text box
for example I want

" the box is very large and brown.
it cannot be crushed."

instead of

"The box is very large and brown. It cannot be crushed."

I need to be able to store that new line info inside of the string array individual parts but I honestly don't know where to start. Any help would be very much appreciated

What I have tried:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class DescriptionOfCard : MonoBehaviour
{

    public Text currentDescription;

    public Text description;

    public int frame = 0;

    string[] descriptionSheet = { "The box is very large and brown." + "It cannot be crushed.", "I literally have over 100 other descriptions" };
    

    void Start()
    {

    }

    public void ChangeDescription()
    {
        description.text = descriptionSheet[0 + frame];

        currentDescription.text = description.text;

        frame = frame + 1;

    }
}
