+## Relay List for Private Content
+
+Kind `10013` indicates the user's preferred relays to store private events like Drafts. The event MUST include a list of `relay` URLs in private tags. Private tags are JSON Stringified, NIP-44-encrypted to the signer's keys and placed inside the .content of the event.
+
+```js
+{
+  "kind": 10013,
+  "tags": [],
+  "content": nip44Encrypt(JSON.stringify([
+    ["relay", "wss://myrelay.mydomain.com"]
+  ]))
+  //...other fields
+}
+```
+
+Relays listed in this event SHOULD be authed and only allow downloads to events signed by the authed user.
+
+Clients SHOULD publish kind `10013` events to the author's [NIP-65](65.md) `write` relays.
