+# Basic Networking Example
+
+This example demonstrates the fundamental networking capabilities of the hypha-network crate, focusing on:
+
+- **Error handling** with `HyphaError` types
+- **Connection establishment** using dial and listen interfaces  
+- **Basic network setup** without complex protocols
+- **Driver pattern** for managing network events
+
+## Features Demonstrated
+
+### Error Handling
+- `HyphaError::DialError` - Connection failures
+- `HyphaError::SwarmError` - Swarm initialization issues
+- Error trait implementations (Display, Debug, Error)
+
+### Networking Traits
+- `DialInterface` - Initiating connections to remote peers
+- `ListenInterface` - Accepting incoming connections
+- `DialDriver` - Processing dial events and connection state
+- `ListenDriver` - Processing listen events and address management
+- `SwarmDriver` - Core event loop and swarm management
+
+### Basic Usage Patterns
+- Creating network interfaces and drivers
+- Setting up asynchronous event processing
+- Managing connection lifecycle
+- Handling network events and errors
+
+## Running the Example
+
+### Demo Mode (Recommended)
+```bash
+cargo run --example basic_networking demo
+```
+
+This creates two in-memory networks, connects them, and demonstrates error handling.
+
+### Server Mode
+```bash
+cargo run --example basic_networking server --listen-addr "/memory/test_server"
+```
+
+### Client Mode  
+```bash
+cargo run --example basic_networking client --server-addr "/memory/test_server"
+```
+
+## Key Concepts
+
+### Driver Pattern
+The example shows the driver pattern used throughout hypha-network:
+- **Interface**: High-level API for applications (`DialInterface`, `ListenInterface`)
+- **Driver**: Event processing and state management (`DialDriver`, `ListenDriver`)
+- **Action**: Commands sent from interface to driver (`DialAction`, `ListenAction`)
+
+### Error Handling
+All networking operations return `Result` types with appropriate error information:
+```rust
+match network.dial(address).await {
+    Ok(peer_id) => println!("Connected to {}", peer_id),
+    Err(e) => eprintln!("Connection failed: {}", e),
+}
+```
+
+### Async Event Processing
+The driver runs an event loop processing both libp2p swarm events and application actions:
+```rust
+tokio::select! {
+    event = self.swarm.select_next_some() => {
+        // Handle libp2p events
+    }
+    Some(action) = self.action_rx.recv() => {
+        // Handle application actions
+    }
+}
+```
+
+## Testing
+
+The example includes unit tests demonstrating:
+- Basic connection setup
+- Error type behavior
+- Memory transport usage for testing
+
+Run tests with:
+```bash
+cargo test --example basic_networking
+```
+
+## See Also
+
+- `request_response` example - Higher-level request-response protocol
+- `crates/network/src/dial.rs` - Dial trait implementation
+- `crates/network/src/listen.rs` - Listen trait implementation
+- `crates/network/src/error.rs` - Error type definitions
