+OpenTelemetry-Python-Contrib
+============================
+
+Complimentary instrumentation and vendor-specific packages for use with the
+Python `OpenTelemetry <https://opentelemetry.io/>`_ client.
+
+.. image:: https://img.shields.io/gitter/room/opentelemetry/opentelemetry-python
+   :target: https://gitter.im/open-telemetry/opentelemetry-python
+   :alt: Gitter Chat
+
+
+**Please note** that this library is currently in _beta_, and shouldn't
+generally be used in production environments.
+
+Installation
+------------
+
+There are several complimentary packages available on PyPI which can be
+installed separately via pip:
+
+.. code-block:: sh
+
+    pip install opentelemetry-exporter-{exporter}
+    pip install opentelemetry-instrumentation-{instrumentation}
+    pip install opentelemetry-sdk-extension-{sdkextension}
+
+A complete list of packages can be found at the 
+`Contrib repo instrumentation <https://github.com/open-telemetry/opentelemetry-python-contrib/tree/master/instrumentation>`_
+and `Contrib repo exporter <https://github.com/open-telemetry/opentelemetry-python-contrib/tree/master/exporter>`_ directories.
+
+Extensions
+----------
+
+Visit `OpenTelemetry Registry <https://opentelemetry.io/registry/?s=python>`_ to
+find a lit of related projects like exporters, instrumentation libraries, tracer
+implementations, etc.
+
+Installing Cutting Edge Packages
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+While the project is pre-1.0, there may be significant functionality that
+has not yet been released to PyPI. In that situation, you may want to
+install the packages directly from the repo. This can be done by cloning the
+repository and doing an `editable
+install <https://pip.pypa.io/en/stable/reference/pip_install/#editable-installs>`_:
+
+.. code-block:: sh
+
+    git clone https://github.com/open-telemetry/opentelemetry-python-contrib.git
+    cd opentelemetry-python-contrib
+    pip install -e ./instrumentation/opentelemetry-instrumentation-flask
+    pip install -e ./instrumentation/opentelemetry-instrumentation-botocore
