+
+## Examples
+
+### Common Workflows
+
+#### 1. Daily Operations
+```bash
+# Check system health
+telecom-cli health
+
+# Review new subscribers
+telecom-cli subscribers list --status new --enhanced
+
+# Check service status
+telecom-cli services list --enhanced
+
+# Review billing
+telecom-cli billing invoices --unpaid
+```
+
+#### 2. Troubleshooting
+```bash
+# Check service logs
+telecom-cli monitoring logs --service api-server --tail 100
+
+# View metrics
+telecom-cli monitoring metrics --service api-server
+
+# Check system resources
+telecom-cli monitoring resources
+```
+
+#### 3. Deployment
+```bash
+# Deploy to staging
+telecom-cli deploy --environment staging
+
+# Monitor deployment
+telecom-cli deploy status --environment staging
+
+# Check health after deployment
+telecom-cli health --environment staging
+```
+
+### Advanced Usage
+
+#### Batch Operations
+```bash
+# Export subscribers to CSV
+telecom-cli subscribers list --format csv > subscribers.csv
+
+# Bulk update subscribers
+while read line; do
+  telecom-cli subscribers update $line
+done < updates.txt
+```
+
+#### Automation Scripts
+```bash
+#!/bin/bash
+# health-check.sh
+
+# Check system health
+if ! telecom-cli health; then
+  echo "System unhealthy!" >&2
+  exit 1
+fi
+
+# Check critical services
+services=("api-server" "charging-engine" "packet-gateway")
+for service in "${services[@]}"; do
+  if ! telecom-cli services show $service | grep -q "running"; then
+    echo "Service $service not running!" >&2
+    exit 1
+  fi
+done
+
+echo "All systems healthy"
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Connection Issues
+```bash
+# Check API endpoint
+telecom-cli config get api-endpoint
+
+# Test connection
+telecom-cli health --verbose
+
+# Check timeout settings
+telecom-cli config get timeout
+```
+
+#### Authentication Issues
+```bash
+# Verify API token
+telecom-cli config get api-token
+
+# Test with different token
+TELECOM_API_TOKEN=new-token telecom-cli health
+```
+
+#### Performance Issues
+```bash
+# Check response times
+telecom-cli health --verbose
+
+# Use JSON format for faster processing
+telecom-cli subscribers list --format json
+```
+
+### Debug Mode
+
+Enable debug mode for detailed troubleshooting:
+
+```bash
+# Enable verbose output
+telecom-cli --verbose subscribers list
+
+# Set debug log level
+telecom-cli config set logging.level debug
+
+# Enable request tracing
+telecom-cli config set api.trace true
+```
