+<1> The `GOOGLE_APPLICATION_CREDENTIALS` environment variable that points to the authentication `key.json` file. The `key.json` file is mounted as a secret volume to the OpenTelemetry Collector.
+<2> Optional project identifier. If not specified, the project is automatically determined from the credentials.
++
+By default, the exporter sends telemetry data to the project specified in the `project` field of the exporter's configuration. You can have an override set up on a per-metric basis by using the `gcp.project.id` resource attribute. For example, if a metric has a label project, you can use the Group-by-Attributes Processor to promote it to a resource label, and then use the Resource Processor to rename the attribute from `project` to `gcp.project.id`.
