All our recipes are here, no exception. Sometimes they are in the contrib repository as well, as a fallback for our plugins.
To use our recipes you just need to add an endpoint in your composer.json.
composer config --no-plugins --json extra.symfony.endpoint '["https://api.github.com/repos/monsieurbiz/symfony-recipes/contents/index.json?ref=flex/master","flex://defaults"]'
Please note that with Sylius you may prefer to use this command instead:
composer config --no-plugins --json extra.symfony.endpoint '["https://api.github.com/repos/Sylius/SyliusRecipes/contents/index.json?ref=flex/main","https://api.github.com/repos/monsieurbiz/symfony-recipes/contents/index.json?ref=flex/master","flex://defaults"]'
