+[extra addons](https://github.com/impress/impress-extras). Extra addons are 3rd party plugins 
+that are not part of impress.js, but that we have nevertheless collected together into the 
+impress-extras repo to provide convenient and standardized access to them. To include 
+the extra addons when checking out impress.js, use git clone --recursive. Even then, they 
+are not activated by default in a presentation, rather each must be included with their own `<script>` tag.
 
 Note: The enabled extra addons are automatically initialized by the *extras*
 plugin.
