Hi @sanfeng-7461, welcome to the Vercel Community!

You can upload various file types to v0 knowledge, including:

• Text files: .txt, .md (markdown)
• Documents: .pdf, .docx
• Code files: .js, .ts, .jsx, .tsx, .py, .css, .html, and other common programming file extensions
• Data files: .json, .csv

The knowledge feature is designed to help v0 understand your project context, documentation, and codebase better so it can provide more relevant assistance.

Let me know if you need any help.
