As with most Content Management Systems, Joomla's true power can only be realized with the use of its vast number of extensions. For help finding extensions to install, watch the previous tutorial. This tutorial will show you how to install and uninstall all types of extensions

To begin, please go to Joomla back-end via this url: "your_site/administrator" (e.g: http://vinaora.com/joomla/administrator/)

• Go to Extensions. Then click Install/Uninstall
• There are three ways you can choose to install an extension.
• The first way is to upload a package file you've already downloaded to your computer. Click Browse. Select the package and click Open. Click Upload File & Install. The plugin has now been installed
• The second way to install an extension is by providing Joomla the path to a folder that contains the extracted contents of the install package. We're not going to do that in this tutorial
• The third and final way to install an extension is provide Joomla with a URL to the package containing the extension. We'll assume you've already found the extension's URL and copied it to your clipboard. Click and drag to select then press CTRL+V to paste over the existing contents of this box. Click Install
• Now, let's uninstall the extension we just installed
• We installed a Component, so click Components. Click the button next to the Component. Look the right. Click Uninstall. The component has been uninstalled
• Note that certain core Joomla components, modules, and plugins, as well as the default language and template, cannot be uninstalled
• That's it! You now know how to install and uninstall extensions in Joomla
