+Additionally, you will need to configure authentication via a
+Service Account. Create your Service Account via the Google
+Cloud Platform control panel, provide it access to the appropriate
+BigQuery datasets, and download the JSON configuration file
+for the service account. In Superset, Add a JSON blob to
+the "Secure Extra" field in the database configuration page
+with the following format ::
+
+    {
+        "credentials_info": <contents of credentials JSON file>
+    }
+
+The resulting file should have this structure ::
+
+    {
+        "credentials_info": {
+            "type": "service_account",
+            "project_id": "...",

+You should then be able to connect to your BigQuery datasets.

 To be able to upload data, e.g. sample data, the python library `pandas_gbq` is required.
