FAQ

Frequently asked questions

Can I start numbering from a number other than 1?

Yes. You can specify any positive integer as the starting number, which is useful when numbering appendices or book chapters.

Which placement positions are available?

You can choose between "Bottom center", "Bottom right", and "Top right".

Will numbering overwrite existing footer text?

Numbers are stamped neatly in the margin area. If your page already has content at the very edge, you can switch between bottom and top placements.
