If you don't own a domain or host a website, set up a github account and use github pages to have a `.well-known/nostr.json` file with the content:

```json
{
  "names": {
    "astroc": "YOURNOSTRPUBKEY"
  }
}
```

Then go to astral.ninja/anigma.io and fill the NIP-05 field with `astroc@<YOURGITHUBUSERNAME>.github.io` 

 Great, thanks ;) I will try
