title: Homebrew install - sudo?
body: <p>I am trying to install Homebrew in my terminal. It first asked me for Password which I typed in (the password I use to login to my computer) and hit enter. Then it comes up with 'Need sudo access on macOS!' - what does this mean? I am already the admin (as far as I know) as this is my personal laptop, noone else uses it. 
  I don't understand what else they need!</p>
  
  <p>My aim is to install git but I can't even get this to install first..</p>
  
  <p>Can anyone help, thanks :)</p>
