+Python Client for Google Cloud Spanner API
+=================================================
+
+Quick Start
+-----------
+
+In order to use this library, you first need to go through the following steps:
+
+1. `Select or create a Cloud Platform project.`_
+2. `Enable billing for your project.`_
+3. Enable the Google Cloud Spanner API.
+4. `Setup Authentication.`_
+
+.. _Select or create a Cloud Platform project.: https://console.cloud.google.com/project
+.. _Enable billing for your project.: https://cloud.google.com/billing/docs/how-to/modify-project#enable_billing_for_a_project
+.. _Setup Authentication.: https://googleapis.dev/python/google-api-core/latest/auth.html
+
+Installation
+~~~~~~~~~~~~
+
+Install this library in a `virtualenv`_ using pip. `virtualenv`_ is a tool to
+create isolated Python environments. The basic problem it addresses is one of
+dependencies and versions, and indirectly permissions.
+
+With `virtualenv`_, it's possible to install this library without needing system
+install permissions, and without clashing with the installed system
+dependencies.
+
+.. _`virtualenv`: https://virtualenv.pypa.io/en/latest/
+
+
+Mac/Linux
+^^^^^^^^^
+
+.. code-block:: console
+
+    python3 -m venv <your-env>
+    source <your-env>/bin/activate
+    <your-env>/bin/pip install /path/to/library
+
+
+Windows
+^^^^^^^
+
+.. code-block:: console
+
+    python3 -m venv <your-env>
+    <your-env>\Scripts\activate
+    <your-env>\Scripts\pip.exe install \path\to\library
