So you pull this git repository into a clean folder then run composer install from the project root.

What happens?

Then when I visit project/public following error display in browser.

   ```Fatal error: Uncaught Error: Class 'Illuminate\Foundation\Application' not found in C:\xampp\htdocs\lns-web-master\bootstrap\app.php:14 Stack trace: #0 C:\xampp\htdocs\lns-web-master\public\index.php(22): require() #1 {main} thrown in C:\xampp\htdocs\lns-web-master\bootstrap\app.php on line 14```

Thats not what I asked
