+Google Cloud Bigtable Python Samples
+===============================================================================
+
+This directory contains samples for Google Cloud Bigtable. `Google Cloud Bigtable`_ is Google's NoSQL Big Data database service. It's the same database that powers many core Google services, including Search, Analytics, Maps, and Gmail.
+
+
+This sample demonstrates using `Stackdriver monitoring`_,
+to scale Cloud Bigtable based on CPU usage.
+
+.. Stackdriver Monitoring: http://cloud.google.com/monitoring/docs
+
+
+.. _Google Cloud Bigtable: https://cloud.google.com/bigtable/docs 
+
+Setup
+-------------------------------------------------------------------------------
+
+
+Authentication
+++++++++++++++
+
+Authentication is typically done through `Application Default Credentials`_,
+which means you do not have to change the code to authenticate as long as
+your environment has credentials. You have a few options for setting up
+authentication:
+
+#. When running locally, use the `Google Cloud SDK`_
+
+    .. code-block:: bash
+
+        gcloud auth application-default login
+
+
+#. When running on App Engine or Compute Engine, credentials are already
+   set-up. However, you may need to configure your Compute Engine instance
+   with `additional scopes`_.
+
+#. You can create a `Service Account key file`_. This file can be used to
+   authenticate to Google Cloud Platform services from any environment. To use
+   the file, set the ``GOOGLE_APPLICATION_CREDENTIALS`` environment variable to
+   the path to the key file, for example:
+
+    .. code-block:: bash
+
+        export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account.json
+
+.. _Application Default Credentials: https://cloud.google.com/docs/authentication#getting_credentials_for_server-centric_flow
+.. _additional scopes: https://cloud.google.com/compute/docs/authentication#using
+.. _Service Account key file: https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount
+
+Install Dependencies
+++++++++++++++++++++
+
+#. Install `pip`_ and `virtualenv`_ if you do not already have them.
+
+#. Create a virtualenv. Samples are compatible with Python 2.7 and 3.4+.
+
+    .. code-block:: bash
+
+        $ virtualenv env
+        $ source env/bin/activate
+
+#. Install the dependencies needed to run the samples.
+
+    .. code-block:: bash
+
+        $ pip install -r requirements.txt
+
+.. _pip: https://pip.pypa.io/
+.. _virtualenv: https://virtualenv.pypa.io/
+
+Samples
+-------------------------------------------------------------------------------
+
+Autoscaling example
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+
+
+
+To run this sample:
+
+.. code-block:: bash
+
+    $ python autoscaler.py
+
+    usage: autoscaler.py [-h] [--high_cpu_threshold HIGH_CPU_THRESHOLD]
+                         [--low_cpu_threshold LOW_CPU_THRESHOLD]
+                         [--short_sleep SHORT_SLEEP] [--long_sleep LONG_SLEEP]
+                         instance_id
+    
+    Scales Bigtable clusters based on CPU usage.
+    
+    positional arguments:
+      instance_id           ID of the Cloud Bigtable instance to connect to.
+    
+    optional arguments:
+      -h, --help            show this help message and exit
+      --high_cpu_threshold HIGH_CPU_THRESHOLD
+                            If Bigtable CPU usages is above this threshold, scale
+                            up
+      --low_cpu_threshold LOW_CPU_THRESHOLD
+                            If Bigtable CPU usages is above this threshold, scale
+                            up
+      --short_sleep SHORT_SLEEP
+                            How long to sleep in seconds between checking metrics
+                            after no scale operation
+      --long_sleep LONG_SLEEP
+                            How long to sleep in seconds between checking metrics
+                            after a scaling operation
+
+
+
+
+The client library
+-------------------------------------------------------------------------------
+
+This sample uses the `Google Cloud Client Library for Python`_.
+You can read the documentation for more details on API usage and use GitHub
+to `browse the source`_ and  `report issues`_.
