Joomla! 內容管理系統可讓您使用擴充功能建立各種類型的網頁。擴充有 5 種基本類型：元件、模組、模板、語言和外掛程式。您的網站包含創建基本英文網站所需的擴充程序，但還有數千種各種類型的附加擴充功能可用。⌈ Joomla! 擴充目錄⌋是 Joomla 最大的擴充目錄。
The Joomla! content management system lets you create webpages of various types using extensions. There are 5 basic types of extensions: components, modules, templates, languages, and plugins. Your website includes the extensions you need to create a basic website in English, but thousands of additional extensions of all types are available. The Joomla! Extensions Directory is the largest directory of Joomla extensions.
元件
元件是較大的擴展功能，可為您的網站產生主要內容。每個元件都有一個或多個「視圖」以控制內容顯示的方式。 Joomla 管理器中還有外加的擴展功能，例如選單、重新導向和擴展管理器。
Components are larger extensions that produce the major content for your site. Each component has one or more "views" that control how content is displayed. In the Joomla administrator there are additional extensions such as Menus, Redirection, and the extension managers.
模組
模組是可以顯示在網頁上的位置的小型內容區塊。該網站上的選單以模組形式顯示。 Joomla! 的核心包括 24 個獨立的模組，從登入到搜尋到隨機圖像。每個模組都有一個以 mod_ 開頭的名稱，但當它顯示時，它會有一個標題。在本節的描述中，標題等同于名稱。
Modules are small blocks of content that can be displayed in positions on a web page. The menus on this site are displayed in modules. The core of Joomla! includes 24 separate modules ranging from login to search to random images. Each module has a name that starts mod_ but when it displays it has a title. In the descriptions in this section, the titles are the same as the names.
模板
模板為您的網站提供了外觀和感覺。他們決定佈局、顏色、字體、圖形和其他設計方面，使您的網站獨一無二。您安裝的 Joomla 預先包裝了三個前端模板和兩個後端模板。
Templates give your site its look and feel. They determine layout, colours, typefaces, graphics and other aspects of design that make your site unique. Your installation of Joomla comes prepackaged with three front end templates and two backend templates. Help
語系
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
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.
外掛
外掛(程式)是任務導向的小型擴展功能，可增強 Joomla!框架。有些與特定擴充功能相關，例如⌈編輯器⌋可以在整個 Joomla 中使用。大多數新手用戶不需要更改隨 Joomla 安裝的任何外掛(程式)。
Plugins are small task oriented extensions that enhance the Joomla! framework. Some are associated with particular extensions and others, such as editors, are used across all of Joomla. Most beginning users do not need to change any of the plugins that install with Joomla. Help
