Currency Rates Update

To parse currency rates for today, use the rake task:

To schedule the rake task to run daily, consider using system utilities like cron. Open the crontab editor:

$ crontab -e

Save the changes and close the editor. This setup will run the rake task every day at 3 AM. Replace /path/to/your/project with the actual path to your project.
