# Localizing your extension {#extension-localization}

The configuration options for localization inside TYPO3 are versatile.
You will find a comprehensive description of all concepts and options in the
[Frontend Localization Guide](https://docs.typo3.org/m/typo3/guide-frontendlocalization/14.3/en-us/Index.html#start).

For the following sections, we assume a correct configuration of the
localization, which is normally done in the
[site configuration](https://docs.typo3.org/permalink/t3coreapi:sitehandling-addinglanguages@14.3).

-   [Multi-language Fluid templates](https://docs.typo3.org/permalink/t3coreapi:multi-language-fluid-templates@14.3)
-   [Localization in PHP](https://docs.typo3.org/permalink/t3coreapi:localization-in-php@14.3)
-   [TypoScript](https://docs.typo3.org/permalink/t3coreapi:typoscript@14.3)
