How Deploy to Cloudflare Works

Here's what happens when you click the button:

Cloudflare creates a copy of this repository in your GitHub or GitLab account
You provide configuration options:
- Project name (e.g. "formzero")
- Database name (e.g. "formzero")
- Auth secret (use jwtsecrets.com or openssl rand -hex 16 to generate one)
Cloudflare builds and deploys FormZero to your account
You get a unique URL (e.g. https://formzero.your-domain.workers.dev) to access your dashboard
