paste that ^ and save as *.sublime-snippet inside sublime/packages/user folder	
		
	
	
// change default server directory *OPTIONAL!
sudo leafpad /etc/apache2/sites-available/000-default.conf

and change the following line to what you want:

DocumentRoot /var/www/html

Also do a
sudo leafpad /etc/apache2/apache2.conf
and find this

<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>

and change /var/www/ to your preferred directory //mine is /var/www/html/work/public

and save it.
After you saved your changes, just restart the apache2 webserver and you'll be done :)
sudo service apache2 restart

// make laravel app to be the landing (localhost) site instead of apache2 /*optional
sudo a2dissite 000-default

CONFIGURE SOME EXTRA STUFF TO MAKE CODING EASIER

//install form and html and input classes

../laravel_folder/composer.json

    "laravelcollective/html": "5.2.*"
}
-----------------------------------------------------

../laravel_folder/config/app.php

// ...

'aliases' => [
// ...
  'Form' => Collective\Html\FormFacade::class,
  'Html' => Collective\Html\HtmlFacade::class,
// ...

------------------------------------------------------
in terminal go to laravel_app_folder and run
sudo composer update

That's it everything set for working with Laravel 5.2

################################################################
// install generators for migrations

sudo composer require laracasts/generators --dev

inside app/Providers/AppServiceProvider.php change public function register

public function register()
{
    if ($this->app->environment() == 'local') {
