+Visit your Langfuse dashboard to view the collected metrics and traces.
+
+## Deployment Guide
+
+### Redis Configuration
+The application requires Redis for caching and queue management. Configure Redis in `application.yml`:
+
+```yaml
+redis:
+  host: "localhost"
+  port: 6379
+  password: ""
+  db: 0
+```
+
+Environment variables can also be used:
+```bash
+REDIS_HOST="localhost"
+REDIS_PORT=6379
+REDIS_PASSWORD=""
+REDIS_DB=0
+```
+
+### Worker Process Management
+The application uses Celery for background task processing. Configure workers in `application.yml`:
+
+```yaml
+celery:
+  workers: 4
+  concurrency: 2
+  max_tasks_per_child: 100
+```
+
+Start workers with:
+```bash
+celery -A jira-webhook-llm worker --loglevel=info
+```
+
+### Monitoring Setup
+The application provides Prometheus metrics endpoint at `/metrics`. Configure monitoring:
+
+1. Add Prometheus scrape config:
+```yaml
+scrape_configs:
+  - job_name: 'jira-webhook-llm'
+    static_configs:
+      - targets: ['localhost:8000']
+```
+
+2. Set up Grafana dashboard using the provided template
+
+### Rate Limiting
+Rate limiting is configured in `application.yml`:
+
+```yaml
+rate_limiting:
+  enabled: true
+  requests_per_minute: 60
+  burst_limit: 100
+```
+
+### Health Check Endpoint
+The application provides a health check endpoint at `/health` that returns:
+
+```json
+{
+  "status": "OK",
+  "timestamp": "2025-07-14T01:59:42Z",
+  "components": {
+    "database": "OK",
+    "redis": "OK",
+    "celery": "OK"
+  }
+}
+```
+
+### System Requirements
+Minimum system requirements:
+
+- Python 3.9+
+- Redis 6.0+
+- 2 CPU cores
+- 4GB RAM
+- 10GB disk space
+
+Required Python packages are listed in `requirements.txt`
