The first thing you should do is set the database connection parameters:
- set the "DB_DATABASE" variable as the name of your database
- set the "DB_USERNAME" variable as the user of your "MySQL" enviroment
- set the "DB_PASSWORD" variable as the password of your "MySQL" enviroment
Once setted the database configuration you should open a command prompt on the root of laravel folder and type : "php artisan serve" this will start the local server
Once started the server you can use the migrate functionality of Laravel to set the tables you are going to use for this project open a new command prompt on the root folder of laravel and type "php artisan migrate" and done!
