Whether you're creating an edX course for your university, or developing a training module for a private organization, there are several online resources available.
EdX maintains an online working reference document titled Building and Running an edX Course; this book was developed in part by using this resource. It is updated often but, on occasion, it might not match the functionality you see in your edX course. That said, it is comprehensive and full of details about edX.
You can find the document Building and Running an edX Course at http://edx.readthedocs.org/projects/edx-partner-course-staff/en/latest/index.html.
There are two Google user groups available for free. Moderated by edX employees and full of skilled professionals—just like you—who create edX courses, both groups are exceptional virtual communities of practice.
To join either group, simply click on the following links, sign in to your Google account, and join the group...
