CoursepPress needs Marketpress to sell courses?

Hi!, i am starting to use this plugins and by mail i have recieved that is good have coursepress and marketpress together, but now that i have been watching a little bit about the Coursepress it seems that it have it owns options to sell the courses without Marketpress.

could i sell the courses without Marketpress?

i have been reading your help in coursepress and it didn't say anything about integration with marketpress.

Is there any video or document talking about this plugins working together from beggining?
