I can't connect to internet

I have Ethernet plugged in my computer and just downloaded Arch Linux using the Minimal profile, I don't understand anything about Linux or Arch but everytime I try to download packages like hyprland (following a YouTube tutorial) an error pops out which I think is internet related. How do I get the Ethernet to work? Linux in my case doesn't have commands like nano or vi because I downloaded the minimal profile (I guess, they can not be found everytime I try writing a command using them) What should I do please help
