The Tutorials page (https://swesmith.com/guides/) has no content - it only shows a heading.

Should display an intro and links to the tutorials.

Suggestion:
Add introductory content or an overview with links to the tutorial sections:

• Build Environments
• Create Instances
• Validation & Evaluation
• Generate Issue Text
• Rate Difficulty
• Train SWE-agents

Happy to collaborate over a PR 🙌
