How to create a website with Joomla
Upload and install extensions:
You can do this simply through the "Extensions" menu. Select "Install/Uninstall" and you will open the Extension Manager. The procedure for uploading various extensions is standard and quick. Just choose the file you need to install and upload it. Extensions must be uploaded as ZIP achives. For example, if you install a module it will be saved in the modules' directory/menu, if you upload plugin – it will be automatically sent in the Plugin menu and so on. The extensions are disabled by default when you upload them. You have to enable them by yourself and manage their settings.
