Sitecore Developer Foundations eLearning: where to find 'adventure company' files

I am doing the Sitecore Developer Foundations eLearning and I'm in the part "Defining Sitecore" where it guides you on using the experience editor and content editor with the example site 'Adventure Company'. But I cannot seem to find where to download the 'adventure company' files/packages.

 

Can anyone point me in the right direction. Thank you very much.
