how to configure a project in laravel to a folder within public_html

I'm doing deploy from a simple project in Laravel to a shared hosting, I did the following steps

1.- create a miproject folder in the root of my shared hosting

2.- I moved the elements of my public folder to public_html/miproject

I've always deploy directly to public_html, but I do not know what steps to follow to make my project accessible from mydomain.com/miproject

index.php

<?php

/**
 * Laravel - A PHP Framework For Web Artisans
 *
 * @package  Laravel
 * @author   Taylor Otwell <taylor@laravel.com>
 */

define('LARAVEL_START', microtime(true));

/*

| Register The Auto Loader

|
| Composer provides a convenient, automatically generated class loader for
| our application. We just need to utilize it! We'll simply require it
| into the script here so that we don't have to worry about manual
| loading any of our classes later on. It feels great to relax.
|
*/

require __DIR__.'/../miproject/vendor/autoload.php';

/*

| Turn On The Lights
|--------------------------------------------------------------------------
|
| We need to illuminate PHP development, so let us turn on the lights.
| This bootstraps the framework and gets it ready for use, then it
| will load up this application so that we can run it and send
| the responses back to the browser and delight our users.
|
*/

$app = require_once __DIR__.'/../miproject/bootstrap/app.php';



/*
|--------------------------------------------------------------------------
| Run The Application
|--------------------------------------------------------------------------
|
| Once we have the application, we can handle the incoming request
| through the kernel, and send the associated response back to
| the client's browser allowing them to enjoy the creative
| and wonderful application we have prepared for them.
|
*/

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

$response->send();

$kernel->terminate($request, $response);

the error message is

Warning: require(/home/sevenstarpe/public_html/barber/../barber/vendor/autoload.php): failed to open stream: No such file or directory in /home/sevenstarpe/public_html/barber/index.php on line 24
