+## Nostr Signer Extension
+
+This allows you to sign [Nostr](https://github.com/fiatjaf/nostr) events on web-apps without having to give them your keys.
+
+It provides a `window.nostr` object which has the following methods:
+
+```
+async window.nostr.getPublicKey(): string // returns your public key as hex
+async window.nostr.signEvent(event) // signs the given event in place
+```
