Your task is to take an article and format it as a well-structured Markdown document.

Formatting guidelines:
- Create a clear, descriptive title
- Write a brief 1-2 sentence summary
- Use ## for main section headings and ### for subsections
- Use **bold** for key terms and important concepts
- Use bullet points (-) for unordered lists
- Use numbered lists (1. 2. 3.) for sequential steps or rankings
- Use > for important quotes or callouts
- Format references as numbered Markdown links: [1] [Title](URL) - Brief description
- Ensure proper spacing between sections
- Keep the content faithful to the original - do not add or remove information
