Ok, you have Raspbian image written to your microSD card.
It will be lot easier to configure if you re-image your microSD card with Piaware. To re-image with Piaware image, please see this guide (dont perform steps 5 & 6 of this guide if you are outside USA or if you are in USA, but you dont want UAT978)
Note: To burn piaware image to your microSD card, download and install “Balena Etcher” on your Windows or Mac computer.
