Where type keys in Laravel 5.5?

Hi!
I am newbie in Laravel, I need to write quick application to learn push notifications technologie (and laravel a little bit).

So:
1.I've created new application via command line
2.Then I've installed davibennun/laravel-push-notification:dev-laravel5 via composer
3.I've run php artisan vendor:publish --provider="Davibennun\LaravelPushNotification\LaravelPushNotificationServiceProvider" --tag="config" (like in READ.me) and I've get Publishing complete
4.I've opened PHPStorm and tried to find config file in project by typing 'Android', path was under vendor: vendor/davibennun/laravel-push-notification/src/config/config.php

It seems that there is something wrong.

Please update README.md for newbies like me. Thank you.
