Enabling wikis with assignments?

I would like to have my students keep a wiki of their project in class. I have provided a starter repository with an assignment on Classrooms. Is there any way to use the wiki functionality with this repo?
The starter repo and forked student repos would be marked as private, which in GH Free does not include wikis, but does the education upgrade allow this?

sorry for late reply but yes. if you upgrade your org with ed discount repos created under it will have wikis even if they are private.
