This edition is made for starting new projects. It is a standard Symfony application, which contains Sylius core as a dependency, making it easy to upgrade.
This installation guide assumes that you are familiar with Composer - Dependency Manager for PHP. Run the following commands in your terminal:
composer create-project sylius/sylius-standard acme
cd acme
php bin/console sylius:install
yarn install
yarn run gulp
php bin/console server:start
open http://127.0.0.1:8000
Sylius is a standard Symfony app, which makes it already highly extendible.
