title: How to add documentation to an exposed property?
body: <p>I'd like to add documentation to my custom Components. This documentation should be visible in the editor.</p>
  
  <p>It seems already available for standard library components :</p>
  
  <p><img src="https://i.stack.imgur.com/pXKjb.png" alt="enter image description here"></p>
  
  <p>However, it doesn't work for my code:</p>
  
  <pre class="lang-cs prettyprint-override"><code>using UnityEngine;
  using System.Collections;
  
  public class MainPlayer : MonoBehaviour {
      // I would like to see this comment in the editor too!
      public string myName;
  
      // Use this for initialization
      void Start () {
          Debug.Log("I am alive and my name is " + myName);
      }
  
      // Update is called once per frame
      void Update () {
  
      }
  }
  </code></pre>
  
  <p>How can I do that?</p>
