+
+### Features Showcase
+
+#### 🌐 Network Health Checker
+```bash
+# Ping monitoring with batch processing
+python -m network_health_checker.cli ping 8.8.8.8 --count 10
+
+# Port scanning
+python -m network_health_checker.cli scan 192.168.1.1 --ports 22,80,443
+
+# DNS queries (all record types)
+python -m network_health_checker.cli dns google.com
+
+# SNMP device queries
+python -m network_health_checker.cli snmp 192.168.1.1 --community public
+
+# Subnet calculations
+python -m network_health_checker.cli subnet 192.168.1.0/24
+```
+
+#### 🔧 SysAdmin Toolkit
+```bash
+# System health monitoring
+python -m toolkit health
+python -m toolkit processes --count 10 --sort cpu
+
+# Log analysis
+python -m toolkit logs /var/log/syslog
+
+# Disk analysis
+python -m toolkit large-files /var/log --min-size 100
+
+# Service management
+python -m toolkit services --state running
+python -m toolkit check-services sshd nginx
+```
+
+#### 📊 Infrastructure Monitoring
+```bash
+# Start the monitoring stack
+cd 2-infra-monitoring
+docker-compose up -d
+
+# Access:
+# - Grafana: http://localhost:3000 (admin/admin)
+# - Prometheus: http://localhost:9090
+# - Alertmanager: http://localhost:9093
+```
+
+#### 💾 Backup Automation
+```python
+from backup_manager import BackupManager, BackupConfig, RetentionPolicy
+
+config = BackupConfig(
+    name="home-backup",
+    source_path="/home/user",
+    destination_path="/backups",
+    retention_policy=RetentionPolicy(keep_daily=7, keep_weekly=4)
+)
+
+manager = BackupManager()
+result = manager.create_backup(config)
+```
+
+#### 💼 M365 Admin Scripts
+```powershell
+# Connect to Microsoft 365
+.\4-m365-admin-scripts\common\Connect-M365.ps1
