+# Google PubSub PHP Sample Application
+
+## Description
+
+Note: The push endpoints don't work with the App Engine's local
+devserver. The push notifications will go to an HTTP URL on the App
+Engine server even when you run this sample locally. So we recommend
+you deploy and run the app on App Engine.
+TODO(tmatsuo): Better implementation for devserver.
+
+## 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 Pub/Sub" API under "APIs & auth > APIs."
+
+- 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 variable.
+
+    GOOGLE_APPLICATION_CREDENTIALS: the file path to the downloaded JSON file.
+
+## Prerequisites
+
+- Install [`composer`](https://getcomposer.org)
+- Install the App Engine Python SDK.
+  We recommend you install
+  [Cloud SDK](https://developers.google.com/cloud/sdk/) rather than
+  just installing App Engine SDK.
+
+- Install Google API client library for PHP into 'lib' directory by running:
+
+```
+$ composer install
+```
+
+## Configuration
+
+- Edit config.json
+    - Replace '{A_UNIQUE_TOKEN}' with an arbitrary secret string of
+      your choice to protect the endpoint from abuse.
+
+    - Replace '{YOUR_PROJECT_ID}' with your project ID
+
+## Deploy the application to App Engine
+
+```
+$ gcloud preview app deploy app.yaml --set-default --project YOUR_PROJECT_ID
+```
+
+Then access the following URL:
+  https://{YOUR_PROJECT_ID}.appspot.com/
+
+## Run the application locally
+
+```
+$ dev_appserver.py -A your-project-id .
+```
