I understand, that in order to contribute to the Shopware platform / core, I have to setup Shopware 6 using the development template.
I followed the steps at https://github.com/shopware/platform#quickstart--installation
But only until
./psh.phar docker:start
I was thinking about installing via bin/console system:setup and bin/console system:install but it fails with
PHP Fatal error: Uncaught Symfony\Component\Dotenv\Exception\PathException:
Unable to read the "/home/projects/shopware-dev-bd/bin/../.env" environment file. in
/home/projects/shopware-dev-bd/vendor/symfony/dotenv/Dotenv.php:567
Is there an easy way to create the .env? Do I have to copy it manually?
