+Cloud Trace Exporter Example
+============================
+
+These examples show how to use OpenTelemetry to send tracing data to Cloud Trace.
+
+
+Basic Example
+-------------
+
+To use this exporter you first need to:
+    * A Google Cloud project. You can `create one here. <https://console.cloud.google.com/projectcreate>`_
+    * Enable Cloud Trace API (aka StackDriver Trace API) in the project `here. <https://console.cloud.google.com/apis/library?q=cloud_trace>`_
+    * Enable `Default Application Credentials. <https://developers.google.com/identity/protocols/application-default-credentials>`_
+
+* Installation
+
+.. code-block:: sh
+
+    pip install opentelemetry-api
+    pip install opentelemetry-sdk
+    pip install opentelemetry-exporter-cloud-trace
+
+* Run example
+
+.. code-block:: sh
+
+    python basic_trace.py
+
+Checking Output
+--------------------------
+
+After running any of these examples, you can go to `Cloud Trace overview <https://console.cloud.google.com/traces/list>`_ to see the results.
+
+* `More information about exporters in general <https://opentelemetry-python.readthedocs.io/en/stable/getting-started.html#configure-exporters-to-emit-spans-elsewhere>`_
