Inline Content (/) Palette

/

• Link - Relative (internal) or absolute (external) links
• Image - Inline images
• Emoji -

  :emoji_name:

  syntax
• Math - LaTeX/KaTeX formulas:

  $$formula$$

• Annotation - Footnote-style explanations

Common Patterns

Create a hint/callout box

{% hint style="info" %}
This is an info hint
{% endhint %}

{% hint style="warning" %}
This is a warning
{% endhint %}

{% hint style="danger" %}
This is a danger/error hint
{% endhint %}

{% hint style="success" %}
This is a success hint
{% endhint %}

Create tabs

{% tabs %}
{% tab title="JavaScript" %}
console.log("Hello");
{% endtab %}
{% tab title="Python" %}
print("Hello")
{% endtab %}
{% endtabs %}

Create expandable section

{% expandable title="Click to expand" %}
Hidden content here
{% endexpandable %}

Create stepper (numbered steps)

{% stepper %}
{% step %}
First step content
{% endstep %}
{% step %}
Second step content
{% endstep %}
{% endstepper %}

Create cards

{% cards %}
{% card title="Card 1" href="/page1" %}
Description here
{% endcard %}
{% card title="Card 2" href="/page2" %}
Another description
{% endcard %}
{% endcards %}

Git Sync Configuration

Enable GitHub Sync

1. Go to space settings → Git Sync
2. Connect GitHub account
3. Select repository and branch
4. Configure sync direction:
   • GitBook → GitHub: GitBook is source of truth
   • GitHub → GitBook: Git repo is source of truth
   • Two-way: Bidirectional sync

Directory structure for Git

docs/
├── README.md          # Space landing page
├── SUMMARY.md         # Table of contents
├── .gitbook.yaml      # GitBook configuration
├── page-one.md
├── group/
│   ├── README.md      # Group landing page
│   └── nested-page.md
└── .gitbook/
    └── assets/        # Images and files

SUMMARY.md structure

# Table of contents

* [Introduction](README.md)
* [Getting Started](getting-started.md)

## Section Title

* [Page One](section/page-one.md)
* [Page Two](section/page-two.md)

.gitbook.yaml configuration

root: ./docs/          # Documentation root directory

structure:
  readme: README.md    # Landing page file
  summary: SUMMARY.md  # Table of contents file

redirects:
  old-path: new-path   # URL redirects

Custom Domain Setup

1. Go to site settings → Custom domain
2. Add your domain (e.g.,

   docs.example.com

   )
3. Configure DNS:
   • CNAME record: Point to

     hosting.gitbook.io

   • Or A record for apex domains
4. Enable HTTPS (automatic via Let's Encrypt)

Subdirectory publishing (with Cloudflare/Vercel)

example.com/docs → GitBook site

OpenAPI Integration

Add OpenAPI specification

1. Upload OpenAPI/Swagger file (JSON or YAML)
2. Or link to hosted spec URL
3. GitBook auto-generates interactive API docs

Customize API reference

{% openapi src="./api.yaml" /%}

Publishing Options

Collaboration

Change Requests

• Create a change request for non-breaking changes
• Request reviews from team members
• Merge when approved
• Automatic conflict detection

Live Edits

• Direct editing for quick fixes
• No approval workflow
• Immediate publishing

Comments

• Inline comments on any block
• @mention team members
• Resolve when addressed

Migration to GitBook

From other platforms

1. Import panel: Confluence, Notion, Docusaurus, Markdown
2. Git Sync: Connect existing Git repo with markdown files
3. Manual: Copy/paste with formatting preserved

Import via Git Sync

# Prepare your repo
mkdir docs
echo "# Welcome" > docs/README.md
echo "* [Welcome](README.md)" > docs/SUMMARY.md
git add . && git commit -m "Initial docs"

Common Issues

Git Sync not working

• Check repository permissions
• Verify branch exists
• Ensure SUMMARY.md is valid
• Check for merge conflicts

Custom domain issues

• Verify DNS propagation (can take 24-48 hours)

  hosting.gitbook.io

• Ensure no conflicting records

Content not updating

• Check for pending change requests
• Verify Git sync status
• Clear browser cache
• Check for merge conflicts
