Route::get('/','ReviewsController@main')->name('main');
Route::post('/','MailController@verify')->name('verifyPost');
Route::get('/reviews', 'ReviewsController@index')->name('reviews');
Route::post('/reviews','ReviewsController@add')->name('addReview');
Auth::routes();
Route::group(['middleware' => 'admin','prefix' => 'admin'],function () {
Route::get('/', 'HomeController@index')->name('admin');
Route::get('/reviews', 'Admin\ReviewsController@get')->name('admin.reviews');
