Topic on Talk:OOUI/Windows/Message Dialogs

I am working on a phabricator task and I need to use OOjs UI/Windows/Message Dialogs for a user warning. 

But 

TypeError: OO.ui.MessageDialog is not a constructor

error occurs at:

var messageDialog = new OO.ui.MessageDialog();

What might be the problem? 

I added `'oojs-ui-core'` and `'oojs-ui-windows'` dependancies in Resources.php

eg:

   'mediawiki.special.movePage' => [
       'scripts' => 'resources/src/mediawiki.special/mediawiki.special.movePage.js',
       'dependencies' => [
           'jquery.byteLimit',
           'mediawiki.widgets',
           'oojs-ui-core',
           'oojs-ui-windows'
       ],
   ],

Now the messeageDialog() is working without an error.

I think the adding dependency part is missing in both mediawiki page (OOjs UI/Windows/Message Dialogs) and documentation page (https://doc.wikimedia.org/oojs-ui/master/js/#!/api/OO.ui.MessageDialog). It should be added for the ease of developers.

This is covered in OOjs UI/Using OOjs UI in MediaWiki#Before you start which is a bold link in the introduction of OOjs UI, but clearly isn't visible enough. Where could we put it to make it easier?

Yeah. I clearly did not notice that since I directly went to the message dialog page.

It is better if every page like this one has s link to the section you mentioned.
