I can't seem to find any instructions on how to install addons to the Document Exchange module. I have installed the addons as a module in my DNN installation, but I can't seem to figure out how to get them to work with DMX. They appear in my list of modules and I can add the addons to a page as a seperate module, but I was under the impression that they would somehow integrate with the DMX module as an "addon". Can someone explain this to me or point me in the direction of some of documentation?
