title: Setting up Environment Variable for GCP
body: <p>I read <a href="https://developers.google.com/identity/protocols/application-default-credentials" rel="nofollow">this</a> article but I still don't understand how I have to set up the environment variable with the <code>.json</code> file with the credentials. Do I have to enter something in the Terminal or write something in my Python code?</p>
  
  <p>Also, is the path relative to the user directory? Thanks</p>
