## What it is
Symfony Flex is a Composer plugin that automates the installation and configuration of Symfony applications and their bundles via a recipe system. It works with the symfony/recipes repository to wire up packages automatically during composer install/require.

## Use cases
- set up a new symfony project quickly
- automatically configure bundles when installing via composer
- manage symfony dependency versions
- scaffold symfony application configuration files
- install symfony packages with auto-configuration recipes

## When to choose
- you are building a Symfony application and want automated bundle configuration
- you want Composer to handle config file setup for Symfony packages
- you need streamlined Symfony project scaffolding

## When to avoid
- you are not using PHP or Composer
- you work outside the Symfony ecosystem and don't want recipe-driven config changes
- you need fully manual control over every package's configuration

## Facets
- artifact type: plugin
- maturity: stable
- function: package-manager, configuration-management, developer-tools, cli
- domain: developer-tools, web-development, backend
- platform: php, cli, cross-platform
- tags: composer-plugin, symfony, recipes, dependency-management, scaffolding, php
