+## Quick Start
+
+Get your C-Relay up and running in minutes with a static binary (no dependencies required):
+
+### 1. Download Static Binary
+
+Download the latest static release from the [releases page](https://git.laantungir.net/laantungir/c-relay/releases):
+
+```bash
+# Static binary - works on all Linux distributions (no dependencies)
+wget https://git.laantungir.net/laantungir/c-relay/releases/download/v0.6.0/c-relay-v0.6.0-linux-x86_64-static
+chmod +x c-relay-v0.6.0-linux-x86_64-static
+mv c-relay-v0.6.0-linux-x86_64-static c-relay
+```
+
+### 2. Start the Relay
+
+Simply run the binary - no configuration files needed:
+
+```bash
+./c-relay
+```
+
+On first startup, you'll see:
+- **Admin Private Key**: Save this securely! You'll need it for administration
+- **Relay Public Key**: Your relay's identity on the Nostr network
+- **Port Information**: Default is 8888, or the next available port
+
+### 3. Access the Web Interface
+
+Open your browser and navigate to:
+```
+http://localhost:8888/api/
+```
+
+The web interface provides:
+- Real-time configuration management
+- Database statistics dashboard
+- Auth rules management
+- Secure admin authentication with your Nostr identity
+
+### 4. Test Your Relay
+
+Test basic connectivity:
+```bash
+# Test WebSocket connection
+curl -H "Accept: application/nostr+json" http://localhost:8888
+
+# Test with a Nostr client
+# Add ws://localhost:8888 to your client's relay list
+```
+
+### 5. Configure Your Relay (Optional)
+
+Use the web interface or send admin commands to customize:
+- Relay name and description
+- Authentication rules (whitelist/blacklist)
+- Connection limits
+- Proof-of-work requirements
+
+**That's it!** Your relay is now running with zero configuration required. The event-based configuration system means you can adjust all settings through the web interface or admin API without editing config files.
+
 ## Web Admin Interface
 
 C-Relay includes a **built-in web-based administration interface** accessible at `http://localhost:8888/api/`. The interface provides:
