Integrations 

Complete Installation first. These guides describe the changes needed when a site uses a particular content or CSS system. They share the same StyleX manifest and Vite entrypoint; none requires a second connector setup.

Use Content Blocks for custom or third-party Content Blocks. Use Fluid Styled Content when TYPO3's standard content elements provide markup or CSS. Use Bootstrap and bootstrap_package for plain Bootstrap CSS or bk2k/bootstrap-package. A project can follow more than one guide.
