+# Google BigTable Sample
+
+## Description
+
+All code in the `src` directory demonstrates how to connect to Cloud Bigtable and run some basic operations to create instance, create cluster, delete instance and delete cluster.
+
+## Build and Run
+1.  **Enable APIs** - [Enable the BigTable API](https://console.cloud.google.com/flows/enableapi?apiid=bigtable)
+    and create a new project or select an existing project.
+2.  **Download The Credentials** - Click "Go to credentials" after enabling the APIs. Click "New Credentials"
+    and select "Service Account Key". Create a new service account, use the JSON key type, and
+    select "Create". Once downloaded, set the environment variable `GOOGLE_APPLICATION_CREDENTIALS`
+    to the path of the JSON key that was downloaded.
+3.  **Clone the repo** and cd into this directory
+    ```sh
+    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+    $ cd php-docs-samples/bigtable/api
+    ```
+
+4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
+    Run `php composer.phar install` (if composer is installed locally) or `composer install`
+    (if composer is installed globally).
+5.  Run `php SNIPPET_NAME.php`. The usage will print for each if no arguments
+    are provided:
+    ```sh
+    $ php src/run_instance_operations.php
+    Usage: php src/run_instance_operations.php PROJECT_ID INSTANCE_ID TABLE_ID
+
+    $ php src/run_instance_operations.php your-project-id your-instance-id your-table-id
+    ```
