Read the forum descriptions. I don't think it's hard to find out that "Feedback" is not the right place, and "Workshop" is. Moved there.
And write a meaningful title for your question. Changed it.
As far as I know, readers that support headers simply generate them themselves, and it's the same header for the whole book. All you can do is provide the right author and title in the metadata.
The ePub format supports some kind of header, but I don't know of any reader that uses it.
