Write chapters. Press Build. Get a book.
Select a chapter, or create your first one.
A part groups chapters under a divider page of its own. Chapters keep numbering straight through — Part II doesn't restart at 1.
These print on the title page, the copyright page, and the covers.
Empty a box and that paragraph is left off the page. You can use {year}, {author}, {title}, {edition} and {rights_holder}.
{year}
{author}
{title}
{edition}
{rights_holder}
Print conventions. Each of these changes the page count, which changes the spine width — rebuild the covers afterwards. Build book does it in the right order.
Setting one clears the other: a finished cover and BookForge's own layout can't both be the front cover. The back cover and spine are always generated, since KDP takes the three as one file.
Nothing has been built yet.
The spine is invisible in the finished cover, because the artwork runs straight through the fold. Magenta marks the two folds, blue the trim, grey the barcode's keep-clear area.
