So if I read the instruction correctly, you should:
After you've set up the model, it's time to create a page where Labels is the Dataview of the page and where you place the widget.
Ofcourse the above is simply an example. Another example would be if you have a Product which can have 1 or more Synonyms. Labels would then become Product and Label would then become Synonym.
For a better understanding of the instructions, make sure you go through the available documentation. (this one on Entities and this one on Associations for example)
