+# Redis Cluster Setup
+
+## Quick Start
+
+1. **Update IP Address**: Replace `192.168.1.33` with your system's IP address in `docker-compose.yml`:
+   ```bash
+   # Find your IP
+   ifconfig | grep "inet " | grep -v 127.0.0.1 | awk '{print $2}' | head -1
+   ```
+
+2. **Start Cluster**:
+   ```bash
+   docker compose up -d
+   ```
+
+3. **Verify Cluster**:
+   ```bash
+   docker exec redis-node-1 redis-cli -p 7001 cluster info
+   ```
+
+## Connection Details
+
+- **Redis Cluster**: `YOUR_IP:7001`, `YOUR_IP:7002`, `YOUR_IP:7003`
+- **RedisInsight UI**: `localhost:5540`
+
+## Clean Restart
+
+To completely reset the cluster:
+```bash
+docker compose down -v
+# Update IP in docker-compose.yml if needed
+docker compose up -d
+```
+
+## External Docker Compose Usage
+
+```yaml
+environment:
+  - REDIS_CLUSTER_URLS=redis://YOUR_IP:7001,redis://YOUR_IP:7002,redis://YOUR_IP:7003
+```
+
+**Important**: Always replace `YOUR_IP` with your actual system IP address.
