# Configuration {#configuration}

-   [Configuration overview](https://docs.typo3.org/permalink/t3coreapi:config-overview@11.5)

features a short description for each topic and links to more information.

We have categorized information about configuration into *configuration
syntax* and *methods*. Configuration that can be changed in the backend
is usually referred to as *Settings*. The [Glossary](https://docs.typo3.org/permalink/t3coreapi:configuration-classification@11.5) explains how we use
these terms in this chapter.
