Modules can be used to display some additional information on pages. Your template offers a couple of module positions where you can plug modules in. Use the Joomla Module Manager to create new module instances and manage the existing ones. Make sure your modules are published and assigned to at least one page to let them appear. Kepp in mind that links to events are determined automatically. The module will try to link to the first menu item which is able to display the event the thumb belongs to.
