This repository is hosting Symfony Flex Recipes for Shopware 6. If you are new to Symfony Flex, please read the blog post.
Each recipe is a directory containing a manifest.json file. The manifest.json file contains the recipe metadata and the list of files to copy.
You can look into the Symfony documentation for more information about the recipe format.
The shopware/platform package is automatically updated by the CI. Change only the core, administration packages.
