# Components

**Berlioz Framework** is built on top of standalone PHP components. Each component can be used **independently** in any
PHP project, without the full framework.

They are all distributed as separate [Composer](https://getcomposer.org/) packages via
[Packagist](https://packagist.org/?query=berlioz).

> All components require **PHP ^8.2** and follow [Semantic Versioning](https://semver.org/).
