Hi @CallieAlreza,

There are a couple different guides that may be useful here.  If you're trying to share just a specific item/module from a course, the How do I share a resource to Commons? - Instructure Community - 1798 guide should cover that.  If you want to share an entire course, the How do I share a course to Commons? - Instructure Community - 1793 should be the one you need.

Let us know if these guides answer your question!
