+Relay List Metadata
+-------------------
+
+`draft` `optional`
+
+Defines a replaceable event using `kind:10002` to advertise relays where the user generally **writes** to and relays where the user generally **reads** mentions.
+
+The event MUST include a list of `r` tags with relay URLs as value and an optional `read` or `write` marker. If the marker is omitted, the relay is both **read** and **write**.
+
+```jsonc
+{
+  "kind": 10002,
+  "tags": [
+    ["r", "wss://alicerelay.example.com"],
+    ["r", "wss://brando-relay.com"],
+    ["r", "wss://expensive-relay.example2.com", "write"],
+    ["r", "wss://nostr-relay.example.com", "read"]
+  ],
+  "content": "",
+  // other fields...
+}
+```
+
+When downloading events **from** a user, clients SHOULD use the **write** relays of that user.
+
+When downloading events **about** a user, where the user was tagged (mentioned), clients SHOULD use the user's **read** relays.
+
+When publishing an event, clients SHOULD:
+
+- Send the event to the **write** relays of the author
+- Send the event to all **read** relays of each tagged user
+- Send the author's `kind:10002` event to all relays the event was published to
+
+### Size
+
+Clients SHOULD guide users to keep `kind:10002` lists small (2-4 relays of each category).
+
+### Discoverability
+
+Clients SHOULD spread an author's `kind:10002` event to as many relays as viable, paying attention to relays that, at any moment, serve naturally as well-known public indexers for these relay lists (where most other clients and users are connecting to in order to publish and fetch those).
