Each document in your book can be numbered, and these numbers can be used as automatic chapter numbers. Automatic will increment from the previous document’s number, or you can choose “Same as Previous in Book” if it’s still the same chapter but broken into two or more parts, or you can arbitrarily number it anything you want to. This can save time if you have a large number of chapters that change order frequently, since the numbers will update automatically.
Each section within an InDesign document can be numbered differently. This allows you to use one type of numerals to consecutively number a document's preface or other introductory materials and another numeral system for the remainder of the document. You must first define your document's sections, and then you can add section markers or page markers to your master pages. Apply the master page to document pages to include the section and page numbers on the document pages.
Inserting page numbers into your InDesign document is quick and simple. The first thing to realise is that InDesign numbers pages according to the page numbers listed in the Pages Panel (Window > Pages). Unless you want to spend the time manually inserting individual page numbers to override this, you should understand how to define sections in your document (see Step 2, below).
Well, no, I didn’t say that I’ve been trying to use chapter numbers. What I’ve been saying is that I’m trying to insert new SECTION numbers. Because according to the official site, InDesign only allows a single chapter per document. For this reason, InDesign offers the workaround of placing and renewing the section marker in multiple locations, even if the word before it is “Chapter”.
In many cases, when you switch to a different numbering format, you want to restart the page numbering at the same time. To restart page numbering, position the insertion point, choose Format > Page > Numbering, and then click the Set Value button to open theValues dialog box (see Figure 3). Notice that you can use this dialog box to restart numbering for pages, chapters, volumes, and secondary pages. Type the new page number in the Set Page Number text box, and choose OK.

One of the last things we need to do is our Table of Contents. We did this earlier, where we had different page numbering. So, all we need to do now is, because we've redefined all our Styles, and we're doing it all proper now, if we go to 'Layout'-- I've got my cursor flashing in here, first of all go to 'Layout', let's go to 'Update Table of Contents', and I'm going to click 'OK'. There's some spaces left in the front of this when I was messing around with it before, yours should be fine. So it's updated to the correct numbers. One thing I also did was I went in and adjusted the font from Medium to Light because I just liked it. I did that in between tutorials.
There are lots of options. For instance, you might reduce the amount of space between the number and the text by changing the Text indent at setting. Or, you might center the heading by choosing Center from the Number alignment dropdown. For even more options, click More to expose several more settings. You could use the Apply changes to option when setting level 1 to the I, II, III numbering style instead of changing it for each level.

This is how our document looks. It’s 16 pages long and has page numbers applied to it, as in Step 1, throughout. You can see that the main text of the book starts on Page 7 of the document, and that the page number marker has adjusted accordingly to mark this as 7. But we want this to be numbered as 1 in the book instead. So, let’s discover how to do just that.
To modify the options, click the Multilevel List option (in the Paragraph Group). Word selects all lists currently in use in the List Library. You'll see two options below the gallery: Define New Multilevel List and Define New List Style. Use the first to create and save a stable custom list style. You'll use the second to change list styles. You can also use the latter to create a new style. So, what's the difference? The Define New List Style option lets you name a style, so you can share, modify, and delete it later. Most users will never need this option. Now, let's move on: choose Define New Multilevel List.
