+# Google Datastore PHP Sample Application
+
+A simple app to make calls to the Datastore API
+
+## Register your application
+
+- Go to
+  [Google Developers Console](https://console.developers.google.com/project)
+  and create a new project. This will automatically enable an App
+  Engine application with the same ID as the project.
+
+- Enable the "Google Cloud Datastore API" under "APIs & auth > APIs."
+
+- edit `app.yaml` and change `MY_GCP_PROJECT_ID` to your App Engine project ID
+
+- For local development also follow the instructions below.
+
+  - Go to "Credentials" and create a new Service Account.
+
+  - Select "Generate new JSON key", then download a new JSON file.
+
+  - Set the following environment variables:
+
+    - `GOOGLE_APPLICATION_CREDENTIALS`: the file path to the downloaded JSON file.
+    - `GCP_PROJECT_ID`: Your app engine project ID
+
+## Prerequisites
+
+- Install [`composer`](https://getcomposer.org)
+- Install Google API client library for PHP by running:
+
+```sh
+composer install
+```
+
+## Run locally
+
+you can run locally using PHP's built-in web server:
+
+```sh
+cd php-docs-samples/datastore
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
+export GCP_PROJECT_ID=my-project-id
+php -S localhost:8080 -t web/
+```
+
+Now you can view the app running at [http://localhost:8080](http://localhost:8080)
+in your browser.
+
+## Deploy to App Engine
+
+**Prerequisites**
+
+- Install the App Engine PHP SDK.
+  We recommend you install
+  [Cloud SDK](https://developers.google.com/cloud/sdk/) rather than
+  just installing App Engine SDK.
+
+**Deploy with gcloud**
+
+```
+$ gcloud preview app deploy app.yaml --set-default --project YOUR_GCP_PROJECT_ID
+```
+
+Then access the following URL:
+  https://{YOUR_GCP_PROJECT_ID}.appspot.com/
+
+### Run for App Engine locally
+
+```
+$ dev_appserver.py -A your-project-id .
+```
