+# Google App Engine Node.js Samples
+
+These are samples for using Node.js on Google App Engine Managed VMs. These
+samples are referenced from the [docs](https://cloud.google.com/appengine/docs).
+
+See our other [Google Cloud Platform github repos](https://github.com/GoogleCloudPlatform)
+for sample applications and scaffolding for other frameworks and use cases.
+
+## Run Locally
+
+Some samples have specific instructions. If there is a README in the sample
+folder, please refer to it for any additional steps required to run the sample.
+
+In general, the samples typically require:
+
+1. Install the [Google Cloud SDK](https://cloud.google.com/sdk/), including the
+[gcloud tool](https://cloud.google.com/sdk/gcloud/), and
+[gcloud app component](https://cloud.google.com/sdk/gcloud-app).
+1. Setup the gcloud tool. This provides authentication to Google Cloud APIs and
+services.
+
+      gcloud init
+
+1. Clone this repo.
+
+      git clone https://github.com/GoogleCloudPlatform/<REPO NAME>.git
+
+1. Open a sample folder, install dependencies, and run the sample:
+
+      cd <sample-folder>/
+      npm install
+      npm start
+
+1. Visit the application at [http://localhost:8080](http://localhost:8080).
+
+## Deploying
+
+Some samples in this repositories may have special deployment instructions.
+Refer to the README file in the sample folder.
+
+1. Use the [Google Developers Console](https://console.developer.google.com) to
+create a project/app id. (App id and project id are identical.)
+1. Setup the gcloud tool, if you haven't already.
+
+      gcloud init
+
+1. Use gcloud to deploy your app.
+
+      gcloud preview app deploy
+
+1. Awesome! Your application is now live at `your-app-id.appspot.com`.

+# Google Analytics Measurement Protocol on Google App Engine
+
+This sample demonstrates how to use the [Google Analytics Measurement Protocol](https://developers.google.com/analytics/devguides/collection/protocol/v1/)
+(or any other SQL server) on [Google App Engine Managed VMs](https://cloud.google.com/appengine).
+
+## Setup
+
+Before you can run or deploy the sample, you need to do the following:
+
+1. Create a Google Analytics Property and obtain the Tracking ID.
+1. Update the environment variables in  in `app.yaml` with your Tracking ID.
+
+## Running locally
+
+Refer to the [appengine/README.md](../README.md) file for instructions on
+running and deploying.
+
+To run locally, set the environment variables via your shell before running the
+sample:
+
+    export GA_TRACKING_ID=<your-tracking-id>
+    npm install
+    npm start
