I am going through Sitecore 9.0 e-learning certification training. I am on course 1 module 2.

How do you set-up the example Adventure site used in the course labs?

It looks like the student resource materials may have some of the right content but it doesn't appear to be the right file types, they are .html files whereas the e-learning approach uses ".cshtml" files, and I can't find any directions on how to include them in the project. 

Are they just there for reference purpose (the lab seems to be indicating that you should be following along)?
