Instead of beginning the document with a right-facing
(recto) page, you can delete the first page and begin your document
with a left-facing (verso) page that’s part of a spread.
Important: Because of the settings necessary to keep
a left-facing page as the starting page, it can be difficult to
insert spreads into a document when following this method. To avoid
this difficulty, it is best to work in the document with a right-facing
page starting page (which should be left blank). When you have inserted
all of the pages needed in the document, delete the first page by
following the steps below.
