How can i make my simple character controller rotate?

im trying to build a controller from the ground up, and im having difficulty getting my character to rotate under input, heres where i am so far

using UnityEngine; using System.Collections;

public class Player : MonoBehaviour {

 public float playerSpeed = 4.0f;
 public float rotationSpeed = 1.0f;
 
 private Vector3 moveDirection = Vector3.zero;
 //public var playerStartPoint = (0.0.0); Can i make Payerspawn public?

 // Use this for initialization
 void Start () {
     
     //Player Spawn point
     transform.position = new Vector3 (0,1,0);
     }
 
 
 void Update () {
     transform.Translate(Vector3.forward * Input.GetAxis("Vertical") * playerSpeed * Time.deltaTime);
     transform.Translate (Vector3.right * Input.GetAxis ("Horizontal") * playerSpeed * Time.deltaTime);
     
     }

}
