+# Pubky Noise Integration Guide
+
+This guide covers integrating the Pubky Noise library into your application for secure, authenticated communication.
+
+## Quick Start
+
+### Installation
+
+Add to your `Cargo.toml`:
+
+```toml
+[dependencies]
+pubky-noise = "0.7"
+```
+
+### Basic Usage
+
+```rust
+use pubky_noise::prelude::*;
+use std::sync::Arc;
+
+// Create key providers
+let client_ring = Arc::new(DummyRing::new([1u8; 32], "client_kid"));
+let server_ring = Arc::new(DummyRing::new([2u8; 32], "server_kid"));
+
+// Create client and server
+let client = NoiseClient::<_, ()>::new_direct("client_kid", b"device", client_ring);
+let server = NoiseServer::<_, ()>::new_direct("server_kid", b"device", server_ring);
+```
+
+## Core Concepts
+
+### Key Providers
+
+The `RingKeyProvider` trait provides cryptographic keys for the Noise handshake:
+
+```rust
+pub trait RingKeyProvider: Send + Sync {
+    fn get_private_key(&self) -> Result<[u8; 32], NoiseError>;
+    fn get_public_key(&self) -> Result<[u8; 32], NoiseError>;
+    fn get_key_id(&self) -> &str;
+}
+```
+
+For testing, use `DummyRing`. For production, implement this trait with secure key storage.
+
+### Handshake Patterns
+
+**IK Pattern** (known server key):
+- Client already knows the server's static public key
+- Faster handshake (2 messages instead of 3)
+- Use when connecting to known servers
+
+**XX Pattern** (trust-on-first-use):
+- Neither party knows the other's key in advance
+- 3-message handshake
+- Use for peer-to-peer connections
+
+### Error Handling
+
+All errors are typed and include error codes for FFI compatibility:
+
+```rust
+use pubky_noise::{NoiseError, NoiseErrorCode};
+
+match result {
+    Err(e) => {
+        let code = e.code();  // For FFI/mobile
+        let msg = e.message(); // Human-readable
+        
+        if e.is_retryable() {
+            if let Some(delay) = e.retry_after_ms() {
+                // Wait and retry
+            }
+        }
+    }
+    Ok(value) => { /* success */ }
+}
+```
+
+### Rate Limiting
+
+Protect your server from DoS attacks:
+
+```rust
+use pubky_noise::{RateLimiter, RateLimiterConfig};
+
+// Use default config or customize
+let limiter = RateLimiter::new(RateLimiterConfig::default());
+
+// Or use predefined configs
+let strict = RateLimiter::new(RateLimiterConfig::strict());
+let lenient = RateLimiter::new(RateLimiterConfig::lenient());
+
+// Check before accepting connections
+let client_ip = "192.168.1.1".parse().unwrap();
+if limiter.check_and_record(&client_ip) {
+    // Accept connection
+} else {
+    // Reject - rate limited
+}
+```
+
+## Mobile Integration
+
+### Using NoiseManager
+
+The `NoiseManager` provides a high-level API for mobile applications:
+
+```rust
+use pubky_noise::{NoiseManager, MobileConfig, ConnectionStatus};
+
+let config = MobileConfig {
+    auto_reconnect: true,
+    reconnect_interval_ms: 5000,
+    max_reconnect_attempts: 10,
+    // ...
+};
+
+let manager = NoiseManager::new(config, key_provider);
+```
+
+### FFI Bindings
+
+Enable UniFFI bindings with the `uniffi_macros` feature:
+
+```toml
+[dependencies]
+pubky-noise = { version = "0.7", features = ["uniffi_macros"] }
+```
+
+## Session Management
+
+### Session IDs
+
+Sessions are identified by a unique 64-bit ID:
+
+```rust
+use pubky_noise::SessionId;
+
+let session = SessionId::new();
+println!("Session: {}", session.id());
+```
+
+### Thread-Safe Session Manager
+
+For multi-threaded applications:
+
+```rust
+use pubky_noise::{ThreadSafeSessionManager, NoiseRole};
+use std::sync::Arc;
+
+let manager = Arc::new(ThreadSafeSessionManager::new());
+
+// Add a session
+manager.add_session(session_id, noise_link, NoiseRole::Initiator);
+
+// Get and use a session
+if let Some(session) = manager.get_session(&session_id) {
+    // Use the session
+}
+```
+
+## Storage-Backed Messaging
+
+For reliable message delivery with persistence (requires `storage-queue` feature):
+
+```rust
+use pubky_noise::{StorageBackedMessaging, MessageQueue, RetryConfig};
+
+let queue = MessageQueue::new(storage_backend);
+let retry_config = RetryConfig {
+    max_retries: 5,
+    base_delay_ms: 1000,
+    max_delay_ms: 30000,
+};
+```
+
+## Security Considerations
+
+1. **Key Storage**: Never hardcode private keys. Use secure storage (Keychain/Keystore).
+
+2. **Rate Limiting**: Always enable rate limiting on servers.
+
+3. **Session Expiry**: Configure appropriate session timeouts.
+
+4. **Error Messages**: Don't expose internal error details to clients.
+
+## Examples
+
+See the `examples/` directory for complete working examples:
+
+- `basic_handshake.rs` - Simple client-server handshake
+- `xx_pattern.rs` - XX pattern handshake
+- `streaming.rs` - Streaming data over Noise
+- `server_example.rs` - Production server setup
+- `mobile_manager.rs` - Mobile app integration
+- `storage_queue.rs` - Reliable messaging with storage
+
+## Troubleshooting
+
+### Common Errors
+
+| Error | Cause | Solution |
+|-------|-------|----------|
+| `RateLimited` | Too many connection attempts | Wait and retry with backoff |
+| `IdentityVerify` | Key verification failed | Check keys match expected |
+| `Timeout` | Connection timed out | Check network, increase timeout |
+| `RemoteStaticMissing` | Server key not available | Use XX pattern or fetch key first |
+
+### Debug Logging
+
+Enable tracing for debugging:
+
+```rust
+// Add tracing subscriber in your app
+tracing_subscriber::fmt::init();
+```
