Fork the registry

Fork the fluxcast-domains repository to your own GitHub account.

Add one JSON file

Create domains/yourname.json. The file name becomes your subdomain, and it holds your owner info and DNS records.

3

Open a pull request

Automated checks validate your file, a maintainer merges it, and yourname.fluxcast.dev goes live within minutes.

// domains/yourname.json
{
    "owner":   { "username": "your-github-username" },
    "records": { "CNAME": "your-github-username.github.io" }
}
