## Overview

Learn how to generate professional documents with an automatic table of contents using Carbone's document generation features. This example shows you how to create well-structured documents that include an organized index, with these key features:

-   Professional document layout
-   Automatic table of contents
-   Organized content structure
-   Automatic chapter numbering

## Step-by-Step Guide

Follow these simple steps to create your document with Carbone:

### 1\. Set Up the Document Format

-   Open the Microsoft Word **File** menu and select **Page Setup**
-   Select a standard paper size from the available options
-   For custom dimensions, use the **Custom Sizes** option

### 2\. Create the Document Structure

-   Use tables to maintain consistent content alignment
-   Insert [Carbone tags](/documentation/design/substitutions/the-basics.md#basic) to display dynamic data, for example:
    -   Use `{d.chapters[i].section}` for chapter titles in the first row
    -   Use `{d.chapters[i+1]}` in the second row for chapter iterations
    -   In table properties, uncheck **Allow row to break across pages** to maintain consistency
-   Format text and adjust spacing for better readability
-   Apply appropriate **Heading** styles (such as **Heading 1**) to sections you want to include in the table of contents

### 3\. Add the Table of Contents

-   In Microsoft Word, go to the **Insert** menu and click the **Field** button
-   Select **Index and Tables** from the **Categories** list
-   Choose **TOC** in the **Field names** section
-   Click **OK** to generate the table of contents

### 4\. Manage Chapters and Subchapters Numbering

-   For chapter numbering, add numbered bullets before the Carbone tag
-   To number subchapters, use the [:print](/documentation/design/formatters/text.md#print-message) formatter to display the [loop iterator value](/documentation/design/repetitions/with-arrays.md#access-the-loop-iterator-value), so it starts at 1 for each chapter.
-   Since array indexes start at 0, add 1 to the iterator value. The complete formula is:  
    `{d.chapters[i].subsections[i].category:print(..i):add(1)}`

That's it! Your document will now have a professional layout with an automatic table of contents.
