+ansible-playbook playbooks/security_audit.yml
+
+# Maintenance (security updates)
+ansible-playbook playbooks/maintenance.yml
+
+# Backup
+ansible-playbook playbooks/backup.yml
+
+# System information gathering
+ansible-playbook playbooks/gather_system_info.yml
+```
+
+### By Environment
+
+```bash
+# Production
+ansible-playbook -i inventories/production site.yml
+
+# Staging
+ansible-playbook -i inventories/staging site.yml
+
+# Development (default)
+ansible-playbook site.yml
+```
+
+### Emergency Procedures
+
+```bash
+# Security incident - assess
+ansible-playbook playbooks/security_audit.yml --limit compromised_host
+
+# Disaster recovery
+ansible-playbook playbooks/disaster_recovery.yml --limit failed_host
+
+# Quick backup before risky operation

+```
+
+## Next Steps (Phase 3 - Not Implemented)
+
+For future implementation:
+- Complete Molecule testing configuration
+- Create integration test playbooks
+- Add pre-commit hooks for ansible-lint
+- Document testing procedures
+- Create additional roles as needed
+
+## Recommendations
+
+1. **Immediate Actions:**

+   - Create vault files from examples
+   - Encrypt vault files: `ansible-vault encrypt inventories/*/group_vars/all/vault.yml`
+   - Test playbooks in development environment
+
+2. **Within 1 Week:**
+   - Schedule regular security audits (weekly)
+   - Schedule maintenance windows (monthly)
+   - Set up automated backups (daily)
+   - Update emergency contact information in runbooks
+
+3. **Within 1 Month:**
+   - Conduct DR drill in staging
+   - Test all playbooks in staging
+   - Train team on new playbooks and procedures
+   - Review and customize group_vars for environments

+```
+
+## Testing
+
+### Local testing
+```bash
+cd /opt/ansible/roles/system_info/tests
+ansible-playbook -i inventory test.yml
+```
+
+### Syntax check
+```bash
+ansible-playbook playbooks/gather_system_info.yml --syntax-check
+```
+
+### Dry run
+```bash
+ansible-playbook playbooks/gather_system_info.yml --check
+```
+
+## Security Considerations
+- Requires sudo/root privileges for hardware information
+- Collects serial numbers, UUIDs (sensitive data)
+- No credentials or secrets are collected
+- Statistics stored on control node only
+- Restrict access to statistics directory appropriately
+
+## Performance
+- Execution time: 30-60 seconds per host
+- Read-only operations - no system changes
+- Low CPU and memory impact
+- Parallel execution supported
+
+## Documentation
+- **Role README**: `/opt/ansible/roles/system_info/README.md`
+- **Cheatsheet**: `/opt/ansible/cheatsheets/system_info.md`
+- **Detailed Docs**: `/opt/ansible/docs/roles/system_info.md`
+
+## Configuration Examples
+
+### Custom statistics directory
+```yaml
+- hosts: all
+  roles:
+    - role: system_info
+      vars:
+        system_info_stats_base_dir: /var/lib/ansible/stats
+```
+
+### Disable specific gathering
+```yaml
+- hosts: servers
+  roles:
+    - role: system_info
+      vars:
+        system_info_gather_gpu: false
+        system_info_gather_network: false
+```
+
+## Integration Examples
+
+### Query all hypervisors
+```bash
+jq -r 'select(.hypervisor.is_hypervisor == true) | .host_info.fqdn' \
+  ./stats/machines/*/system_info.json
+```
+
+### Memory usage report
+```bash
+jq -r '"\(.host_info.fqdn): \(.memory.total_mb)MB total, \(.memory.usage_percent)% used"' \
+  ./stats/machines/*/system_info.json | column -t
+```
+
+### Count total CPU cores
+```bash
+jq -s 'map(.cpu.count.total_cores) | add' \
+  ./stats/machines/*/system_info.json
+```
+
+## Next Steps
+1. Test the role on a sample host
+2. Review and adjust default variables if needed
+3. Integrate with your inventory management
+4. Set up automated collection (cron/AWX/Tower)
+5. Create reports and dashboards from collected data
+

+## Next Steps
+
+1. Test the role on a sample host:
+   ```bash
+   ansible-playbook playbooks/gather_system_info.yml -l localhost
+   ```
+
+2. Verify output files:
+   ```bash
+   ls -la ./stats/machines/$(hostname -f)/
+   cat ./stats/machines/$(hostname -f)/summary.txt
+   jq . ./stats/machines/$(hostname -f)/system_info.json
+   ```
+
+3. Run validation:
+   ```bash
+   ansible-playbook playbooks/gather_system_info.yml -t system_info,validate
+   ```
+
+4. Test selective gathering:
+   ```bash
+   ansible-playbook playbooks/gather_system_info.yml -t system_info,cpu,memory
+   ```
+
+5. Review and customize variables in defaults/main.yml if needed
+
+6. Integrate with your inventory and run across infrastructure
