## What it is
Sulu is an open-source PHP content management system built on the Symfony framework, and this repository contains its core framework that all Sulu projects depend on. It provides an extensible admin interface for managing the full content lifecycle, with strong multilingual and multi-portal (multisite) support and headless/API-first capabilities.

## Use cases
- build a multilingual website with a single CMS installation
- manage multiple websites from one admin backend
- run a headless CMS serving content via API to any frontend
- give editors an intuitive admin interface for content publishing
- manage media assets and SEO metadata for a corporate site
- create localized content with language fallbacks and per-locale SEO

## When to choose
- your team knows PHP and Symfony and wants a full-stack CMS
- you need robust multisite and multilingual features out of the box
- you want an extensible, enterprise-grade CMS with long-term stability
- you need both traditional templated sites and headless content delivery

## When to avoid
- you need a quick blog with minimal setup (WordPress may be simpler)
- your stack is not PHP/Symfony
- you want a fully hosted turnkey CMS with no development work
