Documented steps

  1. Authenticate (fly auth login).
  2. Run `fly launch` from the app source root. It scans the code, generates a Dockerfile/fly.toml, and prompts for name/org/region.
  3. Skip interactive prompts with explicit flags: --name <app>, -o <org>, -r/--region <code>, --generate-name.
  4. Deploy from an existing Docker image with `fly launch -i <image-ref>`.
  5. Limit to scaffolding only (no deploy) with --no-deploy, then deploy separately with `fly deploy`.
  6. Create a new app from a GitHub template repo with `fly launch --from <repo-url> --into <dir>`.
  7. Output config in JSON/YAML with --json or --yaml.
