 You'll also need to activate a couple of APIs in Google Cloud, the first deployment will probably fail and point you into the right direction. Alternatively, you could deploy the first version manually.

+## Updates

+### Web Access

+https://nodejsapi-hkqcqmboga-uc.a.run.app
+https://nodejsapi-hkqcqmboga-uc.a.run.app/site
+
+### Changed GCP action to version 2
+
+This is to fix the deprecation error on version 0 before.
+
+The new version requires different authentication semantics. A separate auth action is added, depending only on the JSON key of an GCP service account, from the `GCP_CREDENTIALS`; `GCP_EMAIL` is no longer needed.
+
+### Workflow change for the forked repo
+
+We add an GitHub environment for storing the deployment credentials. This is added to the `deploy.yml` script, so the workflow can access the credentials variables, including the GCP service account key.
+
+The GCP service account used in this project is created as an Editor role, under a GCP project. It thus only have access to this project and do not need to switch project in the `gcloud` shell.
