The base JICS product comes with several portlets, which are the primary focus of these help pages.
Your portal may also include other portlets that are not detailed in this help system -- these may be portlets that are part of an optional module (and are covered in another help system). Or they might be custom portlets that were built for your institution. In some cases, you can find information on these additional portlets by clicking a help icon in the upper right-hand corner of the portlet window.
