title: How to create multi environment DB's with Firestore
body: <p>I've been looking at how to create multiple Firestore instances in Firebase, I need different Db's for prod, staging and development. I read the documentation and seems that I only need to modify the &quot;Google-services.json&quot; file in the applications. what I don't get is what should I modify and how that would look in the console.</p>
  <ul>
  <li><p>Am I going to see different instances in the same project?</p>
  </li>
  <li><p>I need to create different projects for every environment and modify those values in the file?</p>
  </li>
  <li><p>If I need to test something that requires testing in all environments and all of them require Blaze to run that test do I have
  to pay Triple?</p>
  </li>
  </ul>
  <p>Thanks in advance</p>
