## What is ADF?

**ADF (Atlassian Document Format)** is Confluence's JSON-based document format. It represents content as a structured tree of nodes.

### Basic ADF Structure
```json
{
  "version": 1,
  "type": "doc",
  "content": [
    {
      "type": "paragraph",
      "content": [
        {
          "type": "text",
          "text": "Hello world"
        }
      ]
    }
  ]
}
```

```markdown

```
```json
{

```

**Italic**:

```

## Common Patterns

### README.md to Confluence

1. **Extract title** from first H1
2. **Convert sections** to H2/H3
3. **Preserve code blocks** with language tags
4. **Convert tables** for command reference
5. **Add info panels** for warnings/notes
6. **Link to external resources**

### API Documentation

1. **Endpoint sections** as H2
2. **Parameters** as tables
3. **Code examples** with language highlighting
4. **Response schemas** as code blocks
5. **Status codes** as tables

### Architecture Docs

1. **Diagrams** as images
2. **Decision records** with info panels
3. **Component lists** as bullet lists
4. **Tech stack tables**

## Limitations and Workarounds

### Not Directly Supported

**Markdown feature → Workaround**:

- **HTML tags** → Convert to ADF equivalent or plain text
- **Footnotes** → Use numbered references in text
- **Definition lists** → Use tables or headings
- **Complex nested structures** → Flatten or use expand sections

### Confluence Enhancements

Add these Confluence-specific elements to improve readability:

1. **Info panels** for important notes
2. **Expand sections** for optional details
3. **Status badges** for project status
4. **Task lists** for checklists
5. **Color coding** in tables

## How I'll Help

When converting Markdown to ADF, I will:

1. **Parse the Markdown**: Understand structure and content
2. **Convert to ADF**: Build proper JSON structure
3. **Enhance for Confluence**: Add panels, badges, etc.
4. **Validate**: Ensure valid ADF format
5. **Create/Update**: Use `/confluence-create-page` or `/confluence-update-page`
6. **Preview**: Show you what will be created

## Example Interaction

**You**: "Convert my README.md to a Confluence page"

**Me**: "I'll convert your README.md to Confluence ADF format.

[Reads README.md]

I see:
- Title: "My Project"
- Sections: Overview, Installation, Usage, API Reference
- Code blocks in bash and javascript
- A table of CLI commands
- Some warnings/notes

Converting to ADF with enhancements:
- Converting code blocks with proper language tags
- Tables for command reference
- Info panels for warnings
- Links preserved

Ready to create the Confluence page. Which space should I use?"

**You**: "Space 123456"

**Me**: [Uses `/confluence-create-page` with converted ADF]
"Created page 'My Project' in space 123456!
Link: https://your-domain.atlassian.net/wiki/spaces/123456/pages/..."
