Questions

What happens when I click Create My App?

You download an editable source package with setup files and AI-agent instructions. Your copy is separate from the Foundation Base demo.

Does the Foundation Base demo update when I customize my copy?

No. The demo is the original shared version. Install your own deployed App Link when you want your customized app on a device.

Can I use Claude Code, Codex, Cursor, or another agent?

Yes. Foundations are designed to be opened by an AI coding agent after you download and unzip the source package.
