-               - Install OpenVPN on your server
-               - Generate CA certificates using the script above
-               - Configure firewall to allow VPN traffic
-            
-            2. **Client Configuration:**
-               - Download the generated .ovpn file
-               - Import it into your OpenVPN client
-               - Connect to your server
-            
-            3. **Security Notes:**
-               - Always use strong ciphers (AES-256-GCM)
-               - Enable certificate verification
-               - Keep your certificates secure
