Joomla! 以英語安裝，但介面、範例資料和幫助螢幕的翻譯有多種語言版本。

翻譯訊息

如果沒有適用於您的語言的語言包，可以使用說明來創建您自己的翻譯，您也可以透過組建翻譯團隊來創建經過認可的翻譯來向社區做出貢獻。

使用網站管理員中的擴充功能管理器安裝介面的翻譯，然後使用語言管理器進行管理。

如果您安裝了兩種或多種語言，您可以啟用語言切換器外掛程式和模組。它們應該始終一起使用。如果您建立多語言內容並將您的內容、選單項目或模組標記為特定語言，並遵循完整的說明，您的使用者將能夠使用該模組選擇特定的內容語言。預設情況下，插件和模組均被停用。

Joomla 2.5 安裝了一個語言覆蓋管理器，可讓您更改 Joomla 應用程式中使用的特定單字（例如編輯或搜尋）。

在Joomla!擴充目錄中有許多擴充功能可以幫助您管理 Joomla! 內容的翻譯。

Joomla! installs in English, but translations of the interfaces, sample data and help screens are available in dozens of languages. Help

Translation information

If there is no language pack available for your language, instructions are available for creating your own translation, which you can also contribute to the community by starting a translation team to create an accredited translation.

Translations of the interfaces are installed using the extensions manager in the site administrator and then managed using the language manager.

If you have two or more languages installed you may enable the language switcher plugin and module. They should always be used together. If you create multilingual content and mark your content, menu items or modules as being in specific languages and follow the complete instructions your users will be able to select a specific content language using the module. By default both the plugin and module are disabled.

Joomla 2.5 installs with a language override manager that allows you to change the specific words (such as Edit or Search) used in the Joomla application.

There are a number of extensions that can help you manage translations of content available in the Joomla! Extensions Directory.
