+# Simple spectator bot
+
+A spectator bot connects to the rover server with Socket.IO. It can receive the current session, read chat, and send messages that are visually tagged as bot messages.
+
+## Install
+
+Create a small Node.js project and install the Socket.IO client:
+
+```bash
+npm install socket.io-client
+```
+
+## Example bot
+
+Create `bot.js`:
+
+```js
+import { io } from 'socket.io-client';
+
+// Replace this with the public URL of the MultiRoombaRover server.
+const socket = io('https://your-rover-server.example', {
+  // Match the transports supported by the server while retaining polling as a
+  // fallback for networks or proxies that do not allow WebSocket connections.
+  transports: ['websocket', 'polling'],
+});
+
+// Socket.IO acknowledgements use callbacks. This small wrapper turns them into
+// promises so setup failures and rejected chat messages are easy to handle.
+function emitWithAck(event, payload) {
+  return new Promise((resolve, reject) => {
+    socket.emit(event, payload, (response = {}) => {
+      if (response.error) {
+        reject(new Error(response.error));
+        return;
+      }
+
+      resolve(response);
+    });
+  });
+}
+
+socket.on('connect', async () => {
+  console.log('Connected:', socket.id);
+
+  try {
+    // Set the name that will appear beside this connection and its messages.
+    await emitWithAck('nickname:set', {
+      nickname: 'My spectator bot',
+    });
+
+    // Ask the server to make this passive connection a spectator. Performing
+    // this after every connection also restores the role after a reconnect.
+    await emitWithAck('session:setRole', {
+      role: 'spectator',
+    });
+
+    console.log('Connected as a spectator');
+  } catch (error) {
+    console.error('Spectator setup failed:', error.message);
+  }
+});
+
+// Each session:sync event is a complete current session snapshot. Replace any
+// previously stored session with this object instead of merging snapshots.
+socket.on('session:sync', (session) => {
+  console.log('Session:', session);
+});
+
+// chat:init contains the recent chat history available when the bot connects.
+socket.on('chat:init', (messages) => {
+  console.log('Recent chat:', messages);
+});
+
+// chat:message fires whenever a new message is broadcast, including messages
+// sent by this bot itself.
+socket.on('chat:message', (message) => {
+  console.log(`${message.nickname || 'Unknown'}: ${message.text}`);
+});
+
+socket.on('disconnect', (reason) => {
+  console.log('Disconnected:', reason);
+});
+
+// Setting bot to true adds the normal bot tag to the displayed chat message.
+// It does not grant the connection any additional permissions.
+function sendBotMessage(text) {
+  return emitWithAck('chat:send', {
+    text,
+    bot: true,
+  });
+}
+
+// Send one example message after the connection has had time to finish setup.
+// A real bot would call sendBotMessage from its own message-handling logic.
+setTimeout(() => {
+  sendBotMessage('Hello from my spectator bot!').catch((error) => {
+    console.error('Message failed:', error.message);
+  });
+}, 5000);
+```
+
+Run it with:
+
+```bash
+node bot.js
+```
+
+## Events used
+
+- `nickname:set` sets the bot's visible nickname.
+- `session:setRole` changes the connection to a spectator.
+- `session:sync` provides the latest complete session state.
+- `chat:init` provides recent chat history after connecting.
+- `chat:message` provides new chat messages.
+- `chat:send` sends a chat message. Include `bot: true` to give it the bot tag.
+
+The server can reject spectator access or a chat message. Always check the acknowledgement callback, as the example does, so those errors are not silently ignored.
