route::get('main', 'main@index'); 

main.php

namespace app\http\controller;  use illuminate\http\request;  use app\http\requests; use app\http\controllers\controller;   class main extends contoller {     public function _construct() {         $this->middleware('guest');     }      public function index() {         return "hello world controller";     } } 

if running laravel project locally, can run through own server. dont need apache server form wamp or xampp,,but need mysql database. start if require database.

now go command prompt, navigate directory project stored eg cd c:/wamp/www/yourprojet , type following command

php artisan serve 

it start on port 8000 default. , can access project @ 'http://localhost:8000/'

and can access view @ 'http://localhost:8000/main'

also can find laravel tutorials , other @ laracast
