I have to number the first 4 pages of a document as: i, ii, iii, iv. But the first page should not have a number.

From then on, the pages should read 1, 2, 3, 4, 5 etc. But at each new chapter, I should not have a number on the first page. So numbering starts on the second page of each chapter.

Can you please tell me how to do this? I numbered the first 5 pages but the rest is too difficult. Thank you very much
