With Publications, users can create instance-scoped blocks of changes. Because each publication is instance-scoped, they can be accessed anywhere in the Liferay UI and include changes from multiple Sites. By default, users can only view and manage publications they’ve created. However, users can invite each other to collaborate on their publications. See Collaborating on Publications for more information.
Once Publications is enabled, you can create, edit, publish, or remove a publication via the Publications application page or the Publications drop-down menu.
