Hi there, I just added proper rules to gitignore required for Laravel4, the references are:
Laravel4 Framework itself : http://laravel.com
Laravel4 Framework Documentation : http://laravel.com/docs
Laravel4 Github Repository : https://github.com/laravel/laravel
<b>Sample gitignore file provided by framework core developers : https://github.com/laravel/laravel/blob/master/.gitignore</b>
