 ## Usage
 
 ### Interactive Mode

 4. Exit
 
 ### Automated Mode
-Set `AUTO_MODE="true"` in the `.env` file and run the script. This is suitable for cron jobs.
+Run the script with the `--silent` flag for automated operations:
+```bash
+./certman.sh --silent
+```
+
+### Force Update
+Use the `--force` flag to force certificate updates regardless of current status:
+```bash
+./certman.sh --force
+```
+
+Flags can be combined:
+```bash
+./certman.sh --silent --force
+```
 
 ### Cron Configuration
 Add these lines to your crontab for automated certificate management:
 ```cron
-@reboot sleep 15 && /path/to/certman.sh
+@reboot sleep 15 && /path/to/certman.sh --silent
-5 4 * * 2 /path/to/certman.sh

 ## Security Considerations
 
 - Store the script and `.env` file in a secure location with restricted permissions
 - Use appropriate permissions for certificate and key files
 - Keep API keys secure and rotate them periodically
 - Run the script as a user with appropriate privileges
+- Temporary files are automatically cleaned up using secure practices
+- Certificate and key pairs are validated before installation
