If you see this message, you have not configured your web server properly.
You need to set your "document root" to the 

Code:

public

 folder inside your project. This could be your default setting, or that of a virtual host, depending on how you set up your local development environment.

What's your question? The message is telling you to, in a nut-shell, run the site from the public folder. What are you using as a webserver? Apache? NGINX? PHP's built-in server?
