Usage

There's no need to configure anything before running the application. There are 2 different ways of running this application depending on your needs:

Option 1. Download Symfony CLI and run this command:

cd my_project/
symfony serve

Then access the application in your browser at the given URL (https://localhost:8000 by default).

Option 2. Use a web server like Nginx or Apache to run the application (read the documentation about configuring a web server for Symfony).

On your local machine, you can run this command to use the built-in PHP web server:

cd my_project/
php -S localhost:8000 -t public/

Tests

Execute this command to run tests:

cd my_project/
./bin/phpunit
