Volo's Guide Maps/Lairs?

I just bought Volo's Guide on Roll20 marketplace, but I can't find the lairs that are in the hardback book.  When I bought it said I'd be able to import them into my game.  Specifically, I'd like to port the orc lair into my existing homebrew campaign. Does anyone know how I can can do this?

Game addons it will put all map into your game i think

Thom is correct. Any and all maps will be added into the game along with any and all handouts, journals, etc.. material in the appropriate locations when the addon is placed in the game.

As a side note, Volo's also includes a module that you can use to create a new game. While this won't put the maps into the games you have already made as the Addon will, it is a great way to create a blank campaign where you can see the maps etc. This has the bonus of also creating a page with all of the Volo monster tokens laid out as well. Especially great if you have access to the Transmogrifier as an option for moving maps, handouts, and monsters between campaigns.

Thanks everyone.  I didn't realize that I needed the extra step after buying Volo of adding it.  I feel like Monster Manual added automatically. Now I just have to figure out how to work lighting hiding a map with whatever settings are automatically there. That, and I stock the dungeon:)
