Edit an Affinity Publisher user manual PDF
Manuals are long and change in small ways: a menu name, a version number, a support email. Fix those in the PDF and split the manual into chapters if people need only part of it. If it was made in Affinity Publisher, you can edit the PDF itself. Frames edit independently and keep their alignment.
