title: How to update site changes on GCP from GitHub website
body: <p>I have been helping a friend make some changes to their website. The people that developed it before hosted it on GCP, and all code was pushed to GitHub. I was given ownership of the Git repository and invited by my friend to the GCP.</p>
  <p>However, I do not know how to push the changes that are in the Git repository to the GCP to update the live site. I have taken a look through some tutorials, but they all show how to do it from scratch, but of course, this has already been done before and I am not sure if things are the same.</p>
  <p>I have checked the source repository section in the GCP console, and there is nothing there. I am also locked out of the Firestore.</p>
  <p>Could someone explain how I go about updating the live site with my changes committed to GitHub.</p>
  <p>Thanks</p>
