The Annual Update Checklist is the easiest way to review your app content each year, in order to make sure that everything is up-to-date and ready to go for the new year.
It's also used for setting up your app initially.
It lists all the sections of your app, shows a report on whether that app content has been set up, and links to the relevant Dashboard Guide pages.
You can find it at the end of the Content block on the Dashboard home page, or visit this link.
