+# Google Cloud Logging Samples
+
+This section contains samples for [Google Cloud Logging](https://cloud.google.com/logging).
+
+## Running the samples
+
+In order to run it, your environment must be setup with [authentication
+information](https://developers.google.com/identity/protocols/application-default-credentials#howtheywork). If you're running it in your local development environment and you have the [Google Cloud SDK](https://cloud.google.com/sdk/) installed, you can do this easily by running:
+
+    $ gcloud auth login
+
+## Additional resources
+
+For more information on Cloud Logging you can visit:

+
+For more information on the Clloud Logging API Python library surface you
+can visit:
