Purchasing a module, Such as Storm King's Thunder or a bundle of add-ons such as Tales from the Yawning Portal will give you everything you need to run the adventure. For modules, simply select it when starting a new campaign, and it will build the campaign with all necessary Maps (Including dynamic lighting for plus and pro memebers), Handouts, NPC Character sheets, and so on. All the information from the book is provided in Inter-linked handouts, so that the book isn't necessary. For Add-ons, you can add each of the modules to your existing game via the Game Addons section of the Game Settings page: This includes the Characters, Handouts, and Pages. They will be in your game as if you had created them, or dragged them in from the compendium.
