What's the best way to do this?
Is this Vlad? I'm in your discord if someone from the team can drop a mention of this npub for Nostr. Or, we can help walk you through setting up a nip05 identifier for the Kagi domain.
It is him. Vlad posted the link.
On your website post a nostr link to your npub. Maybe combined with njump. i.e. You could use a nostr logo by @mbarulli https://github.com/mbarulli/nostr-logo cc @fiatjaf
The BEST was would be better to setup a Nostr address with your domain. It's just one line of code. https://github.com/nostr-protocol/nips/blob/master/05.md Otherwise, you can just add a link to your Nostr profile on your website somewhere that is applicable.
