How to change currency in nopCommerce?

By default, the currency displayed on the site is USD, and I'd like to change it to my own country currency, which is MYR.

This is how I changed:

1. Go to Administration > Configuration > Currencies

2. If your currency is already in the list, just publish or mark it as primary store currency, otherwise click on Add New button to add a new currency.

3. This is the setting I created for my own country currency.

4. As we do not provide the currency exchange feature, so I just un-publish the other currencies, but just published this newly created currency.
