Hello nerds,
If you want to start your new CakePHP project with Twitter Bootstrap set with it, you can follow the steps as following:-

Step 1: You need to Download CakePHP and Twitter Bootstrap versions. You can easily download them from their websites or from the below link-
CakePHP --> https://github.com/cakephp/cakephp/tags
Twitter Bootstarp-->http://getbootstrap.com/getting-started/#download

Step 2: After extracting the both downloaded folders you need to copy all files from Twitter Bootstrap to CakePHP folders.

For example every css file in twitter bootstrap should copy to css folder in webroot of cakephp similarly all the js files need to copy to js folder.

Step 3. Now you have all most done in this step you just need to setup your default.ctp file in cake.php

For Example, replace the <meta charset="utf-8"> with <?php echo $this>Html->charset(); ?>. Then remove the static title with

<title>
<php echo $title_for_layout; ?>
</title>  

Continue on with the conversion and you will end up this file.
