TL;DR

Added a new 'Integrations' section to the documentation, featuring a detailed guide for deploying Kernel applications with Vercel.

Why we made these changes

To provide clear instructions and a pre-configured template for users to easily deploy Kernel applications on Vercel, enhancing integration capabilities.

What changed?

• docs.json: Introduced a new 'Integrations' group in the documentation structure, including a new page entry for 'integrations/vercel'.
• integrations/vercel.mdx: A new file detailing the official Vercel integration, covering quick start, API key setup, agent deployment, monorepo structure, features (chatbot, browser automation), and use cases.

Validation

• mintlify dev works locally.

What Changed

This PR introduces a new "Integrations" section to the documentation and adds a comprehensive guide for deploying Kernel applications on Vercel. A new page, integrations/vercel.mdx, details the process using a dedicated template, covering everything from initial setup and API key configuration to the project's monorepo structure. This is a great addition that provides a clear path for users to deploy their applications on a popular platform.

Risks / Concerns

Overall, this is a solid contribution. There are a couple of minor inconsistencies in the new documentation that could be polished to prevent user confusion:

• In integrations/vercel.mdx, a link on line 73 points to a local file path ([route](packages/web/app/api/chat/route.ts)) instead of a documentation page.
• The repository name is inconsistent between the git clone command and the directory structure example (line 15 vs. line 48).

The link text [route](packages/web/app/api/chat/route.ts) appears to be referencing a file path within the template repository rather than a documentation link. This might be confusing for users since it's not a clickable link to actual documentation. Consider either removing the link formatting or linking to relevant documentation about routes.

Minor inconsistency: The directory structure shows kernel-vercel-template/ but the git clone command above (line 15) clones vercel-template.git. Consider ensuring the naming is consistent throughout the documentation.
