Click on menu:Add books[Add empty book]. Then fill in the metadata and select
“EPUB” as format. You can add more metadata and a cover image by right-clicking
the book and then selecting menu:Edit metadata[]. Open Calibre's editor by right
clicking on the book and selecting menu:Edit book[]. You start with a single XHTML
file, `start.xhtml`. I always use that for the title page, the copyright notice
and so on. You can force a page break to separate the title and the copyright
notice with CSS: Add `style="page-break-after: always;"` to the last element of
the virtual “page” or use a CSS class. To add a CSS file click menu:File[New
file] and enter a filename ending with `.css`. Add the CSS file to the document
by right clicking on `start.xhtml` in the file browser and selecting

Calibre creates EPUB 2 books by default. Convert the book to EPUB
3footnote:[EPUB 3 introduces many accessibility features, see
link:{url-ap-semantics}[AccessiblePublishing: EPUB Semantics, ARIA Roles, &
Metadata] for details.] by clicking menu:Tools[Upgrade book internals]. This
will, among other things, convert `toc.ncx` to `nav.xhtml`. To support e-book
readers which can't handle EPUB 3 yet, re-create `toc.ncx` as an empty file. It
is filled automatically when you create the table of Contents. Open
`metadata.opf` and replace `<spine>` with `<spine toc="id1">` (`id1` is the ID
of `toc.ncx`, defined a few lines above).
