In this guide, the term "eXo add-on" denotes anything that enhances the eXo extensibility - is developed and distributed by eXo or any third-parties or any individual developers. An add-on may comprise a set of extensions, customizations, xml configurations, applications, templates or any new services.
In eXo Platform, you can perform various extensibilities, for example, portal extension to extend portal, UIComponent plugin to add another UI component (Wiki actions, Activity types), or search connector.
