Need Video Add Ckeditor To Yii Framework

Dear friends,

I follow this site to add ckeditor to yii framework but it still not there any video tutorial to instruct step by step for this issue ?

thankyou very much

Dear friends,

for add ckeditor to yii framework, these steps I have done:

first: download ckeditor standard 4.2 and TheCKEditor

second : I put ckeditor folder to project besite protected folder and copy TheCKEditor to extends 

in TheCKEditor there are 2 files theCKEditorWidget.php, one in TheCKEditor/theCKEditorWidget.php and one in TheCKEditor/views/theCKEditorWidget.php

thirst: I copy the theCKEditorWidget.php which is TheCKEditor/theCKEditorWidget.php to ckeditor.

next I put this code in the view:

<?php $this->widget('application.extensions.TheCKEditor.theCKEditorWidget',array(

		    'model'=>$model,                # Data-Model (form model)

		    'attribute'=>'vn_shortDescription',         # Attribute in the Data-Model



		    'toolbarSet'=>'Basic',          # EXISTING(!) Toolbar (see: ckeditor.js)


		                                    # Path to ckeditor.php


		                                    # Relative Path to the Editor (from Web-Root)

		    'css' => Yii::app()->baseUrl.'/css/index.css',

		                                    # Additional Parameters

		) ); ?>

but I receive error :

Alias "application.extensions.TheCKEditor.theCKEditorWidget" is invalid. Make sure it points to an existing PHP file and the file is readable. 

I do not know what step is wrong, hope you help me to fix this issue.

thankyou very much
