This is used to add zig docs support!

The PR has not yet been completed, but zig-webui actually has a more detailed API document.

I wonder if you can assign a subdomain name to this? @hassandraga

In fact, the documentation generated by zig's automatic documentation generator is more accurate and easier to maintain.

I prefer not to because all wrappers will have different subdomains and different documentation. It's better to have one unified documentation for all supported languages, and this shows more WebUI's potential.

No, I don't think so. All auto-generated docs are simple. They only take the API's name and copy the above comment. Auto-generated docs are definitely quicker and time-saving, but manual handwriting documentation is more professional, detailed, and descriptive for each API.
