Walkthrough

This pull request updates the documentation site: it adds two new integration pages (docs/src/integrations/kernel.mdx and docs/src/integrations/steel.mdx), updates docs/src/docs.json to include those pages in the Integrations group, augments the quickstart (docs/src/intro/quickstart.mdx) with an "Advanced Script" step and reorders a tip, and restructures and rewrites content in docs/src/intro/what-is-notte.mdx (new intro text, a "Why Notte?" section, and reorganized key features).

🧹 Nitpick comments (1)

58-61: Minor style suggestion: Consider rewording line 61 for clarity.

The phrase "if they matter for your use case" could be more direct (e.g., "if required for your use case" or "when needed"). This is optional.

🔇 Additional comments (4)

docs/src/docs.json (1)

65-67: LGTM!

The integration navigation entries are correctly formatted and reference the new documentation files. The ordering (cursor, kernel, steel) appears intentional and logical.

docs/src/integrations/kernel.mdx (1)

1-77: Excellent integration guide.

The Kernel integration documentation is comprehensive, well-structured, and includes appropriate caveats about API compatibility. Code examples are clear and follow Notte SDK patterns correctly.

docs/src/integrations/steel.mdx (1)

1-77: Excellent integration guide with good Steel-specific details.

The Steel integration documentation is well-structured and mirrors the Kernel guide appropriately. The guidance on API key handling and query parameters is clear and accurate.

docs/src/intro/what-is-notte.mdx (1)

8-14: Excellent restructuring with clear value proposition.

The new "Why Notte?" section effectively explains the platform's approach (combining deterministic scripts with adaptive agents), and the reorganized Key Features into Web Automation, Browser infrastructure, and Security & Identity categories significantly improves readability and navigation.
