## Usage

To use the Currency Converter, follow these simple steps:

1. **Select Currency**: The default currency for conversion is set to HKD (Hong Kong Dollar). Use the dropdown menu to select the currency you want to convert to.
2. **Enter Amount**: Type in the amount you wish to convert in the input field.
3. **Convert**: Click the 'CONVERT' button to get the conversion result.
4. **Popular Currencies**: Use the popular currency buttons to quickly set the conversion currency without using the dropdown. This will only change the conversion target currency and not the original HKD currency.
5. **Swap Currencies**: Use the 'Swap' button if you need to switch the selected currencies in the dropdown menus.

## Error Handling

If you enter an amount less than or equal to zero, the extension will display an error message:
ERROR: Accept only amount larger than zero, please try again.

Simply enter a new amount greater than zero to proceed with the currency conversion.

Happy converting!
