Initial clone and build

[moqca]

Hello!
I was trying to build the app but came across a couple errors:

1. the initial clone command git clone https://github.com/kareemaladawy/laravel.git errors our. Should that be https://github.com/kareemaladawy/laravel-quiz-system instead?
2. When using the second option, getting to php artisan migrate --seed errors out as:
   SQLSTATE[HY000] [2002] Connection refused (Connection: mysql, SQL: select * from information_schema.tables where table_schema = quiz_system and table_name = migrations and table_type = 'BASE TABLE')

Not sure if the database is not spinning up.
Looking at .env there are several settings that need to be configured. Which ones are 100% required?

Thank you!
