Sulu is a highly extensible open-source PHP content management system based on the Symfony framework. Sulu is developed to deliver robust multi-lingual and multi-portal websites while providing an intuitive and extensible administration interface to manage the full content lifecycle.

Have a look at the official Sulu website for a comprehensive list of Sulu's features, core values and use cases.

This repository contains the core framework of the Sulu content management system. The framework implements the functionality that is built into the Sulu content management system and therefore is a dependency of all Sulu projects.

If you want to start a new Sulu project, you might be interested in the sulu/skeleton template repository. If you are planning to extend your existing Sulu project, visit the Sulu organization on GitHub for a complete list of official Sulu bundles.

The sulu/skeleton repository provides a pre-configured project template to quick-start your development. Visit the official Sulu documentation to find out how to use the project template for starting your own Sulu project.
