Hi,
In Providence, go to NEW, COLLECTION.
There, give a title for the collection, write a description, then save. In ADMIN, don't forget to change the status to accessible to public. Save.
Create a NEW, OBJECT, with a title, and create a relation to the collection. Make it accessible to public.
Then go to Pawtucket web site and try to find the object or the collection. Sometime, you need to delete all temporary files in the app/cache directory of Pawtucket.
