-**Content Topic**: `/toy-chat/2/huilong/proto`.
-
-This specification explains a toy chat example using Waku v2.
-This protocol is mainly used to:
-
-1. Dogfood Waku v2,
-2. Show an example of how to use Waku v2.
-
-Currently, all main Waku v2 implementations support the toy chat protocol:
-[nim-waku](https://github.com/status-im/nim-waku/blob/master/examples/v2/chat2.nim),
-js-waku ([NodeJS](https://github.com/status-im/js-waku/tree/main/examples/cli-chat) and [web](https://github.com/status-im/js-waku/tree/main/examples/web-chat))
-and [go-waku](https://github.com/status-im/go-waku/tree/master/examples/chat2).
-
-Note that this is completely separate from the protocol the Status app is using for its chat functionality.
-
-# Design
-
-The chat protocol enables sending and receiving messages in a chat room.
-There is currently only one chat room, which is tied to the content topic.
-The messages SHOULD NOT be encrypted.
-
-The `contentTopic` MUST be set to `/toy-chat/2/huilong/proto`.
-
-# Payloads
-
-```protobuf
-syntax = "proto3";
-
-message Chat2Message {
-   uint64 timestamp = 1;
-   string nick = 2;
-   bytes payload = 3;
-}
-```
-
-- `timestamp`: The time at which the message was sent, in Unix Epoch seconds,
-- `nick`: The nickname of the user sending the message,
-- `payload`: The text of the messages, UTF-8 encoded.
