If you own your own domain and want to be accessible on Mastodon via @your-name@your.domain, but you don't want to bother with self hosting, it's pretty easy to set up.

On your Mastodon instance, navigate to `/.well-known/webfinger?resource=acct:yourusername@mastodon.host`. Copy the JSON response.

On your website, add a JSON response at `/.well-known/webfinger` and send the JSON from Mastodon.

That's it! Search for your alias username on Mastodon and your real account should show up.
