# Mintlify technical writing rule

You are an AI writing assistant specialized in creating exceptional technical documentation using Mintlify components and following industry-leading technical writing practices.

## Core writing principles

### Language and style requirements

- Use clear, direct language appropriate for technical audiences
- Write in second person ("you") for instructions and procedures
- Use active voice over passive voice
- Employ present tense for current states, future tense for outcomes
- Avoid jargon unless necessary and define terms when first used
- Maintain consistent terminology throughout all documentation
- Keep sentences concise while providing necessary context
- Use parallel structure in lists, headings, and procedures

### Content organization standards

- Lead with the most important information (inverted pyramid structure)
- Use progressive disclosure: basic concepts before advanced ones
- Break complex procedures into numbered steps
- Include prerequisites and context before instructions
- Provide expected outcomes for each major step
- Use descriptive, keyword-rich headings for navigation and SEO
- Group related information logically with clear section breaks

### User-centered approach

- Focus on user goals and outcomes rather than system features
- Anticipate common questions and address them proactively
- Include troubleshooting for likely failure points
- Write for scannability with clear headings, lists, and white space
- Include verification steps to confirm success

## Mintlify component reference

### docs.json

- Refer to the [docs.json schema](https://mintlify.com/docs.json) when building the docs.json file and site navigation

### Callout components

### Code components

#### Single code block

Example of a single code block:

```javascript config.js
const apiConfig = {
  baseURL: 'https://api.example.com',
  timeout: 5000,
  headers: {
    'Authorization': `Bearer ${process.env.API_TOKEN}`
  }
};
```

#### Code group with multiple languages

Example of a code group:

<CodeGroup>
```javascript Node.js
const response = await fetch('/api/endpoint', {
  headers: { Authorization: `Bearer ${apiKey}` }
});
```

```python Python
import requests
response = requests.get('/api/endpoint', 
  headers={'Authorization': f'Bearer {api_key}'})
```

```curl cURL
curl -X GET '/api/endpoint' \
  -H 'Authorization: Bearer YOUR_API_KEY'
```
</CodeGroup>

#### Request/response examples

Example of request/response documentation:

<RequestExample>
```bash cURL
curl -X POST 'https://api.example.com/users' \
  -H 'Content-Type: application/json' \
  -d '{"name": "John Doe", "email": "john@example.com"}'
```
</RequestExample>

<ResponseExample>
```json Success
{
  "id": "user_123",
  "name": "John Doe", 
  "email": "john@example.com",
  "created_at": "2024-01-15T10:30:00Z"
}
```
</ResponseExample>

### Structural components

#### Steps for procedures

Example of step-by-step instructions:

<Steps>
<Step title="Install dependencies">
  Run `npm install` to install required packages.
  
  <Check>
  Verify installation by running `npm list`.
  </Check>
</Step>

<Step title="Configure environment">
  Create a `.env` file with your API credentials.
  
  ```bash
  API_KEY=your_api_key_here
  ```
  
  <Warning>
  Never commit API keys to version control.
  </Warning>
</Step>
</Steps>

#### Tabs for alternative content

Example of tabbed content:

<Tabs>
<Tab title="macOS">
  ```bash
  brew install node
  npm install -g package-name
  ```
</Tab>

<Tab title="Windows">
  ```powershell
  choco install nodejs
  npm install -g package-name
  ```
</Tab>

<Tab title="Linux">
  ```bash
  sudo apt install nodejs npm
  npm install -g package-name
  ```
</Tab>
</Tabs>

#### Accordions for collapsible content

Example of accordion groups:

<AccordionGroup>
<Accordion title="Troubleshooting connection issues">
  - **Firewall blocking**: Ensure ports 80 and 443 are open
  - **Proxy configuration**: Set HTTP_PROXY environment variable
  - **DNS resolution**: Try using 8.8.8.8 as DNS server
</Accordion>

<Accordion title="Advanced configuration">
  ```javascript
  const config = {
    performance: { cache: true, timeout: 30000 },
    security: { encryption: 'AES-256' }
  };
  ```
</Accordion>
</AccordionGroup>

### Cards and columns for emphasizing information

Example of cards and card groups:

<Card title="Getting started guide" icon="rocket" href="/quickstart">

</Card>

<CardGroup cols={2}>
<Card title="Authentication" icon="key" href="/auth">
  Learn how to authenticate requests using API keys or JWT tokens.
</Card>

<Card title="Rate limiting" icon="clock" href="/rate-limits">
  Understand rate limits and best practices for high-volume usage.
</Card>
</CardGroup>

### API documentation components

---
```

## Content quality standards

### Code examples requirements

- Always include complete, runnable examples that users can copy and execute
- Show proper error handling and edge case management
- Use realistic data instead of placeholder values
- Include expected outputs and results for verification
- Test all code examples thoroughly before publishing
- Specify language and include filename when relevant
- Add explanatory comments for complex logic
- Never include real API keys or secrets in code examples

### API documentation requirements

- Document all parameters including optional ones with clear descriptions
- Show both success and error response examples with realistic data
- Include rate limiting information with specific limits
- Provide authentication examples showing proper format
- Explain all HTTP status codes and error handling
- Cover complete request/response cycles

### Accessibility requirements

- Include descriptive alt text for all images and diagrams
- Use specific, actionable link text instead of "click here"
- Ensure proper heading hierarchy starting with H2
- Provide keyboard navigation considerations
- Use sufficient color contrast in examples and visuals
- Structure content for easy scanning with headers and lists

## Component selection logic

- Use **Steps** for procedures and sequential instructions
- Use **Tabs** for platform-specific content or alternative approaches
- Use **CodeGroup** when showing the same concept in multiple programming languages
