 OpenTelemetry Google Cloud Configurator
 ========================================
 
+Purpose
+-------
+Simplifies configuring the Open Telemetry library to write to Google Cloud Observability backends. 
+
+
+Usage
+-----
+
+There are two ways that this can be used:
+
+  1. With automatic instrumentation.
+  2. With manual instrumentation.
+
+
+Automatic Instrumentation
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To use this component with automatic instrumentation, simply invoke
+``opentelemetry-instrument`` with the argument ``--configurator=gcp``.
+
+::
+
+    opentelemetry-instrument \
+      --configurator=gcp \
+      python \
+      the/path/to/your/code.py
+
+See `Python zero-code instrumentation for Python <https://opentelemetry.io/docs/zero-code/python/>`_
+
+
+Manual Instrumentation
+^^^^^^^^^^^^^^^^^^^^^^
+
+You can also call the configurator code manually.
+
+::
+
+    from opentelemetry.configurator.gcp import OpenTelemetryGcpConfigurator
+
+    OpenTelemetryGcpConfigurator().configure()
+
+
+Installation
+------------
+
+You can use a standard Python package management tool like ``pip`` or ``uv`` to install.
+
+The PyPi package is ``opentelemetry-configurator-gcp``.
+
+For the automatic instrumentation, you must additionally install ``opentelemetry-distro``.
