After this you should see a contents page, click save and continue once again. Then under categories select server content, click save and continue. Select items that work together from the 'What kind of collection is this' option. Set a name for your collection and load a branding image if you have one, followed by a short description.

You'll then want to go to community, and then workshop. The contents of your collection can then be downloaded in it's entirety when you start the server.
