+## Important Warnings and Security Practices
+
+Before executing any commands in this documentation, please adhere to the following guidelines to ensure the security and integrity of the system:
+
+1. **Execute Commands with Caution**: Always review and understand a command before executing it. Misuse of commands can lead to data loss or system instability.
+2. **Backup Command Execution**: The backup command must be executed only by authorized users. Ensure that proper permissions are set to prevent unauthorized access to backup files.
+3. **Regular Backups**: Maintain regular backups of all critical data. It is advisable to use automated backup solutions and verify backup integrity periodically.
+4. **System Updates**: Regularly update the system and all installed packages to protect against vulnerabilities. Use the package manager responsibly to avoid potential conflicts.
+5. **Monitor System Logs**: Continuously monitor system logs for any unusual activity. Use logging tools to help identify potential security breaches or system failures.
+6. **User Permissions**: Ensure that user permissions are strictly managed. Limit access to sensitive commands and data to only those who need it to perform their job functions.
+7. **Network Security**: Implement proper network security measures, such as firewalls and intrusion detection systems, to protect against external threats.
+8. **Data Encryption**: Encrypt sensitive data at rest and in transit to prevent unauthorized access.
+
+By following these practices, you will help maintain the security and stability of the system while minimizing the risk of data loss or compromise.

+    systemctl status nginx
+    ```
+
+    Visit the server at [http://<hostname-internet>](http://<hostname-internet>) or [https://<hostname-internet>](https://<hostname-internet>).
+
+19. **Backup post installation**
