 ## Step-by-Step
 1. Edit `src/index-master.html` or `src/nostr-master.html` if you need custom content.
 2. Run `voxvera init` and follow the prompts, or use `voxvera init --from-pdf path/to/form.pdf`.

For a quick test you can run `python3 -m http.server` inside the folder and then visit the provided address.
