With the extension repository, you can easily install and maintain TYPOlight extensions in the back end at the push of a button (from version 2.6.2). The extension repository has been developed by Peter Koch.
The extension lists contains all available TYPOlight extensions. You can search the list and download the modules you are interested in. You can also write extension reviews.
Reviews are evaluations written by other community members. They are supposed to help you figure out how popular, reliable or usable an extension is in the opinion of other users.
