In this tutorial, we learn how to install plug-ins on a Joomla website. First, download the AllVideos plug-in through extensions.joomla.org. To upload, go to the extension manager and then enable to plug-in. Now, go to extensions, then plug-in manager. Once here, you will have access to all your plug-ins. From here, you can control which ones you want enabled and disabled. After you do this, you will be able to use the plug-in that you just uploaded to your website. Do this with all the different plug-ins you would like and you're finished!
