 ### Options
 
 - **-d my_database**: Specifies the name of the database you want to export. Replace `my_database` with the actual name of your database.
-
 - **-i 3600**: Sets the interval (in seconds) for the dump process. In this example, the interval is set to 3600 seconds (1 hour). You can adjust this value based on your requirements.
-
 - **-f /path/to/**: Indicates the file path where the dump will be saved. Replace `/path/to/` with the desired directory path on your system.
+- **--encrypt**: (Optional) Encrypts the dump file using AES-256 encryption. This option requires a password to encrypt and decrypt the dump file.
 
 ### Example
 
 To create a dump of a database named `example_db` with an interval of 2 hours and save it to the `/backups/` directory, you would run:
 
 ```bash
-dumpsync export -d example_db -i 7200 -f /backups/
+dumpsync export
+```
+
+### Encrypt Dumps
+
+To create an encrypted dump file, you can add the `--encrypt` option to the command:
+
+```bash
+dumpsync export --encrypt
 ```
 
+The encryption process use AES-256 encryption and will prompt you to enter a password for the encryption and decryption of the dump file.
+
 ### Notes
 
+- The export process will create a dump file of the specified database at the specified interval.
+- If you choose to encrypt the dump file, you will need to provide a password during the encryption process.
 - Ensure that the specified path for the dump exists and that you have the necessary permissions to write to that directory.
 - Adjust the interval according to your backup strategy to ensure that you have up-to-date dumps without overwhelming your database resources.
