## Site Information

- **Author**: Russell Ballestrini
- **Site URL**: {site_url}
- **Generated**: {datetime.now().isoformat()}

## Feeds (Recommended for Crawling)

### Atom Feed
- URL: {site_url}/feeds/all.atom.xml
- Format: Atom XML
- Description: Complete feed of all blog posts, newest first

### JSON Feed (jsonfeed.org v1.1)
- URL: {site_url}/feeds/all.json
- Format: JSON Feed 1.1
- Description: Same as Atom feed, but JSON for easier parsing

### JSON Blog (jsonblog.dev)
- URL: {site_url}/blog.json
- Format: JSON Blog
- Description: **Entire blog in one file** - all posts with content_url links to index-slim.md (Markdown)

## Content Formats

Each article is available in multiple formats:
- **HTML**: `/{{slug}}/index.html` - Rendered page with styling
- **RST**: `/{{slug}}/index.rst` - reStructuredText source
- **Markdown**: `/{{slug}}/index.md` - GitHub-flavored Markdown
- **Plain Text**: `/{{slug}}/index.txt` - Raw text, no markup (best for LLMs)

## API-Friendly Endpoints

### Resume (JSONResume Format)
- URL: {site_url}/uploads/russell.ballestrini.resume.json
- Format: JSONResume standard schema
- Description: Structured resume data in machine-readable format

## Navigation Structure

### By Category
"""

    if categories:
        for cat in categories[:15]:
            content += f"- [{cat}]({site_url}/category/{cat}/)\n"

    content += f"""
### By Tag
"""

    if tags:
        for tag in tags[:30]:
            content += f"- [{tag}]({site_url}/tags/{tag}/)\n"

    content += f"""
## Crawling Recommendations

1. **Start with the Atom feed** for a complete list of articles
2. **Use .md or .rst formats** for cleaner text extraction (less HTML noise)
3. **Rate limit requests** - be respectful, this is a personal blog
4. **Cache responses** - content doesn't change frequently

## Topics Covered

- Python programming & web frameworks (Pyramid, Flask, Django)
- DevOps & Infrastructure (Salt, Ansible, AWS, Terraform)
- Cloud computing & containerization
- System administration & Linux
- Software architecture & best practices
- Entrepreneurship & side projects
- Security & networking
