+[shell_link]: https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/GoogleCloudPlatform/python-docs-samples&page=editor&open_in_editor=error_reporting/fluent_on_compute/README.md
+
+This section contains samples for [Google Cloud Error Reporting](https://cloud.google.com/error-reporting).
+
+A startup script has been provided to demonstrated how to properly provision a GCE 
+instance with fluentd configured. Note the intallation of fluentd, the addition of the config file,
+ and the restarting of the fluetnd service. You can start an instance  using
+it like this:
+
+    gcloud compute instances create example-instance --metadata-from-file startup-script=startup_script.sh
+
+or simply use it as reference when creating your own instance.
+
+After fluentd is configured, main.py could be used to simulate an error:
+
+    gcloud compute copy-files main.py example-instance:~/main.py
+
+Then, 
+
+    gcloud compute ssh example-instance
+    python ~/main.py
+
+And you will see the message in the Errors Console.
+

+These samples are used on the following documentation page:
