how do you get the Greek keyboard?
It depends on what type of device you are using. If you are using a laptop or computer, then you can search online, or at the bottom of the Greek Course description, to learn exactly how to change your keyboard. If you are using a phone or mobile device, then you can go to settings and add a keyboard.
