wen i add litstack to my laravel app i get following warning after typing command:

• composer require litstack/litstack
• php artisan lit:install

Class ParsedownExtraTest located in ./vendor/erusev/parsedown-extra/test/ParsedownExtraTest.php does not comply with psr-0 autoloading standard. Skipping.

Maybe someone could fix this? i think it does not affect anything, but looks confusing ;)
