Number a PDF, including from page 3
Position on the page, number format, starting page: the three settings that make numbering land correctly. The format is written with variables — "{n} / {total}" gives "4 / 12" — and the starting page handles the common case of a cover that should not count.
Like the watermark, numbering is a structural addition: the page's existing content is left alone.

Questions about “Page numbers”
Can I start numbering at page 3?
Yes: the starting page is an explicit setting, precisely for documents whose cover and contents page should not count.
How do I show "4 / 12" rather than "4"?
Write the format as "{n} / {total}": {n} is replaced by the page number, {total} by the document's page count.
Can I number several PDFs at once?
Yes, the whole batch runs as one job. And a document merged a moment earlier can be numbered without being saved first.
