+# Connecting to the WebSocket
+
+This guide explains how to connect to the OpenHands WebSocket API to receive real-time events and send actions to the agent.
+
+## Overview
+
+OpenHands uses [Socket.IO](https://socket.io/) for WebSocket communication between the client and server. The WebSocket connection allows you to:
+
+1. Receive real-time events from the agent
+2. Send user actions to the agent
+3. Maintain a persistent connection for ongoing conversations
+
+## Connecting to the WebSocket
+
+### Connection Parameters
+
+When connecting to the WebSocket, you need to provide the following query parameters:
+
+- `conversation_id`: The ID of the conversation you want to join
+- `latest_event_id`: The ID of the latest event you've received (use `-1` for a new connection)
+- `providers_set`: (Optional) A comma-separated list of provider types
+
+### Connection Example
+
+Here's a basic example of connecting to the WebSocket using JavaScript:
+
+```javascript
+import { io } from "socket.io-client";
+
+const socket = io("http://localhost:3000", {
+  transports: ["websocket"],
+  query: {
+    conversation_id: "your-conversation-id",
+    latest_event_id: -1,
+    providers_set: "github,gitlab" // Optional
+  }
+});
+
+socket.on("connect", () => {
+  console.log("Connected to OpenHands WebSocket");
+});
+
+socket.on("oh_event", (event) => {
+  console.log("Received event:", event);
+});
+
+socket.on("connect_error", (error) => {
+  console.error("Connection error:", error);
+});
+
+socket.on("disconnect", (reason) => {
+  console.log("Disconnected:", reason);
+});
+```
+
+## Sending Actions to the Agent
+
+To send an action to the agent, use the `oh_user_action` event:
+
+```javascript
+// Send a user message to the agent
+socket.emit("oh_user_action", {
+  type: "message",
+  source: "user",
+  message: "Hello, can you help me with my project?"
+});
+```
+
+## Receiving Events from the Agent
+
+The server emits events using the `oh_event` event type. Here are some common event types you might receive:
+
+- User messages (`source: "user", type: "message"`)
+- Agent messages (`source: "agent", type: "message"`)
+- File edits (`action: "edit"`)
+- File writes (`action: "write"`)
+- Command executions (`action: "run"`)
+
+Example event handler:
+
+```javascript
+socket.on("oh_event", (event) => {
+  if (event.source === "agent" && event.type === "message") {
+    console.log("Agent says:", event.message);
+  } else if (event.action === "run") {
+    console.log("Command executed:", event.args.command);
+    console.log("Result:", event.result);
+  }
+});
+```
+
+## Using Websocat for Testing
+
+[Websocat](https://github.com/vi/websocat) is a command-line tool for interacting with WebSockets. It's useful for testing your WebSocket connection without writing a full client application.
+
+### Installation
+
+```bash
+# On macOS
+brew install websocat
+
+# On Linux
+curl -L https://github.com/vi/websocat/releases/download/v1.11.0/websocat.x86_64-unknown-linux-musl > websocat
+chmod +x websocat
+sudo mv websocat /usr/local/bin/
+```
+
+### Connecting to the WebSocket
+
+```bash
+# Connect to the WebSocket and print all received messages
+echo "40{}" | \
+websocat "ws://localhost:3000/socket.io/?EIO=4&transport=websocket&conversation_id=your-conversation-id&latest_event_id=-1"
+```
+
+### Sending a Message
+
+```bash
+# Send a message to the agent
+echo '42["oh_user_action",{"type":"message","source":"user","message":"Hello, agent!"}]' | \
+websocat "ws://localhost:3000/socket.io/?EIO=4&transport=websocket&conversation_id=your-conversation-id&latest_event_id=-1"
+```
+
+### Complete Example with Websocat
+
+Here's a complete example of connecting to the WebSocket, sending a message, and receiving events:
+
+```bash
+# Start a persistent connection
+websocat -v "ws://localhost:3000/socket.io/?EIO=4&transport=websocket&conversation_id=your-conversation-id&latest_event_id=-1"
+
+# In another terminal, send a message
+echo '42["oh_user_action",{"type":"message","source":"user","message":"Can you help me with my project?"}]' | \
+websocat "ws://localhost:3000/socket.io/?EIO=4&transport=websocket&conversation_id=your-conversation-id&latest_event_id=-1"
+```
+
+## Event Structure
+
+Events sent and received through the WebSocket follow a specific structure:
+
+```typescript
+interface OpenHandsEvent {
+  id: string;           // Unique event ID
+  source: string;       // "user" or "agent"
+  timestamp: string;    // ISO timestamp
+  message?: string;     // For message events
+  type?: string;        // Event type (e.g., "message")
+  action?: string;      // Action type (e.g., "run", "edit", "write")
+  args?: any;           // Action arguments
+  result?: any;         // Action result
+}
+```
+
+## Best Practices
+
+1. **Handle Reconnection**: Implement reconnection logic in your client to handle network interruptions.
+2. **Track Event IDs**: Store the latest event ID you've received and use it when reconnecting to avoid duplicate events.
+3. **Error Handling**: Implement proper error handling for connection errors and failed actions.
+4. **Rate Limiting**: Avoid sending too many actions in a short period to prevent overloading the server.
+
+## Troubleshooting
+
+### Connection Issues
+
+- Verify that the OpenHands server is running and accessible
+- Check that you're providing the correct conversation ID
+- Ensure your WebSocket URL is correctly formatted
+
+### Authentication Issues
+
+- Make sure you have the necessary authentication cookies if required
+- Verify that you have permission to access the specified conversation
+
+### Event Handling Issues
+
+- Check that you're correctly parsing the event data
+- Verify that your event handlers are properly registered
