To use a document set in a library, you must first add it to the list of content types supported by the library. Once that is done, you can create document set folders just like you would create regular folders except you will have the ability to add information into any of the columns the document set content type defined.
The following walk-through will show you how to add the new Course Documents content type to the Documents library and create an instance of the document set in the library.
The Allow management of content types setting might already be set to Yes from an earlier walk-through.
Once the steps from the preceding walk-through have been completed, you can then upload various documents that go with the course. For example, PowerPoint slides, setup guide, course manual, course outline, etc. Additionally the Welcome Page can be edited and customized.
