+# Server-Worker Network Setup Guide
+
+## System Components
+
+### 1. Server (server.py)
+
+```python
+from ceylon import Admin
+
+app = Admin(name="admin", port=8888, role="admin")
+
+
+@app.on_run()
+async def run_worker(inputs: bytes):
+    while True:
+        await app.broadcast_message("Hello World from Server")
+```
+
+The server broadcasts messages continuously to all connected workers.
+
+### 2. Worker (worker_agent.py)
+
+```python
+from ceylon import Worker
+
+worker = Worker(name="worker", port=8888, role="worker")
+
+
+@worker.on(str)
+async def on_message(agent_id: str, data: str, time: int):
+    print(f"Received message from {agent_id}: {data} at {time}")
+```
+
+The worker listens for and processes messages from the server.
+
+### 3. Configuration (.ceylon_network)
+
+```
+WORKSPACE_ID=default
+WORKSPACE_IP=127.0.0.1
+WORKSPACE_PEER=12D3KooWMrqMLuYL3vExw7qaBJRzjN43kkkZwqSxUog7oaQCmnFE
+WORKSPACE_PORT=8888
+```
+
+## Setup Instructions
+
+1. Start the Server:
+   ```bash
+   python server.py
+   ```
+    - Server creates .ceylon_network file with connection details
+    - WORKSPACE_PEER is auto-generated unique identifier
+
+2. Start Worker(s):
+   ```bash
+   python worker_agent.py
+   ```
+    - Worker reads .ceylon_network file
+    - Connects to server using WORKSPACE_PEER
+
+## Remote Connection Setup
+
+1. Copy .ceylon_network to remote machine
+2. Update WORKSPACE_IP if needed
+3. Run worker_agent.py on remote machine
+
+## Network Configuration
+
+- Default port: 8888
+- Local IP: 127.0.0.1
+- For remote connections:
+    - Update WORKSPACE_IP to server's IP
+    - Ensure port 8888 is accessible
+
+## Common Issues
+
+1. Connection Failures
+    - Verify .ceylon_network file exists
+    - Check WORKSPACE_IP and port accessibility
+    - Ensure WORKSPACE_PEER matches server
+
+2. Network Constraints
+    - Configure firewalls to allow port 8888
+    - Use correct IP for non-local connections
+
+## Security Notes
+
+- WORKSPACE_PEER acts as unique identifier
+- Keep .ceylon_network secure for controlled access
+- Update configuration for production environments
