The language handling in TYPO3 is built in layers. That means all languages are handled on the same page, and not built in separate trees. The site is created in the default language and then a page is translated into selected language, which will then let you translate the default elements on that page. It is also possible to create pages shown in one language or have different elements on a translated page. This also allows you to see if a change has been made in the default language, through a notification. This manual will guide you to these different approaches.
