Cloning Laravel GitHub Repository

I’m new in working with Laravel and I want to clone a GitHub Laravel project to see how it works. I executed the commands: git clone, composer install and php artisan serve. I do get the laravel development server URL, but when I tried to run the project on the browser I get a server error 500. I feel that I’m missing some commands, If so, could you tell me which ones?

I appreciate your help.
