Extensions are similar to Apps on an iPhone. You install them and they integrate into Joomla, expanding the functionality of your Joomla site. Extensions can be as simple as image galleries, but many extensions are very powerful and can transform your site into an eCommerce solution or facebook style social site.
Extensions are downloaded from the Joomla Extensions Directory (JED), you may hear some people refer to this as the JED(Joomla Extensions Directory). There are thousands of extensions available for download.
Some extensions are free, and some cost money. In some cases we recomend going with the commercial extensions simply because the developers of that extension are more likely to offer you support and provide updates if needed. However, there are many great free extensions as you will see.
Installing an extension is as simple as uploading the file into your Joomla site. Be sure that your extension is compatible with your version of Joomla. Learn how to install an extension.
We focus our main support on Joomla. As you can understand, there is no way we could become experts at using all extensions that are out there. So we encorage you to request support from the developers of the extensions. In most cases, extension developers will include a forum for questions and documentation on using the extension.
