iWork has dozens of templates. Choose one when opening a new document by pressing Command + Shift + N or navigate to File | New from Template Chooser.
Each template has finished pages, which we can adapt for our own publishing projects. We just have to add new images and text to replace the ones in the template, to create our own customized version. This allows us to create beautiful documents with astonishing speed. We can add just a few elements of our own—a photo or a logo—or create a completely different look by modifying the template.
Even when we design our project from scratch, that is, from a blank document, we can make selected elements of our document behave like templates.
