+# Google Cloud IoT Core NodeJS Samples
+
+This folder contains NodeJS samples that demonstrate an overview of the Google
+Cloud IoT Core platform.
+
+## Quickstart
+
+1.  Install the Google Cloud SDK as described in [the device manager guide](/iot/docs/device_manager_guide#install_the_gcloud_cli).
+1.  Create a Cloud Pub/Sub topic:
+
+    gcloud beta pubsub topics create projects/my-iot-project/topics/device-events
+
+1.  Add the service account `cloud-iot@system.gserviceaccount.com` to that
+    Cloud Pub/Sub topic from the [Cloud Developer Console](https://console.cloud.google.com)
+    or by setting the `GOOGLE_CLOUD_PROJECT` environment variable and using the
+    helper script in the `scripts/` folder.
+
+1.  Create a registry:
+
+        gcloud alpha iot registries create my-registry \
+            --project=my-iot-project \
+            --region=us-central1 \
+            --pubsub-topic=projects/my-iot-project/topics/device-events
+
+1.  Use the `generate_keys.sh` script to generate your signing keys:
+
+        ./scripts/generate_keys.sh
+
+1.  Create a device.
+
+        gcloud alpha iot devices create my-node-device \
+            --project=my-iot-project \
+            --region=us-central1 \
+            --registry=my-registry \
+            --public-key path=rsa_cert.pem,type=rs256
+
+1.  Connect a sample device using the sample app in the `mqtt_example` folder.
+1.  Learn how to manage devices programatically with the sample app in the
+    `manager` folder.

+# Google Cloud IoT Core NodeJS Device Management example
+
+This sample app demonstrates device management for Google Cloud IoT Core.
+
+Note that before you run this sample, you must configure a Google Cloud PubSub
+topic for Cloud IoT as described in the parent README.
+
+# Setup
+
+Run the following command to install the library dependencies for NodeJS:
+
+    npm install
+
+# Running the sample
+
+The following command summarizes the sample usage:
+
+      Usage: cloudiot_device_manager_example [options]
+
+      Example Google Cloud IoT device manager integration
+
+      Options:
+
+        -h, --help                                     output usage information
+        --project_id <project_id>                      GCP cloud project name.
+        --pubsub_topic <pubsub_topic>                  Cloud Pub/Sub topic to use.
+        --api_key <api_key>                            Your API key.
+        --ec_public_key_file <ec_public_key_file>      Path to EC public key.
+        --rsa_certificate_file <rsa_certificate_file>  Path to RSA certificate file.
+        --cloud_region <cloud_region>                  GCP cloud region.
+        --service_account_json <service_account_json>  Path to service account JSON file.
+        --registry_id <registry_id>                    Custom registry id. If not provided, a unique registry id will be generated.
+
+For example, if your project ID is `blue-jet-123`, your service account
+credentials are stored in your home folder in creds.json and you have generated
+your credentials using the shell script provided in the parent folder, you can
+run the sample as:
+
+    node cloudiot_device_manager_example.js \
+        --service_account_json=$HOME/creds.json \
+        --api_key=YOUR_CLIENT_ID \
+        --project_id=blue-jet-123 \
+        --pubsub_topic=projects/blue-jet-123/topics/device-events \
+        --ec_public_key_file=../ec_public.pem \
+        --rsa_certificate_file=../rsa_cert.pem

+/**
+ * Example of using the Google Cloud IoT Core device manager to administer
+ * devices.
+ *
+ * This example uses the Device Manager API to create, retrieve, disable, list
+ * and delete Cloud IoT Core devices and registries, using both RSA and
+ * elliptic curve keys for authentication.
+ *
+ * To start, follow the instructions on the Developer Guide at
+ * cloud.google.com/iot to create a service_account.json file and API key.
+ *
+ * Register your device as described in the parent README.
+ *
+ * Usage example:
+ *
+ *   $ npm install
+ *   $ nodejs cloudiot-device-manager-example.js \
+ *       --project_id=my-project-id \
+ *       --pubsub_topic=projects/my-project-id/topics/my-topic-id \
+ *       --api_key=YOUR_API_KEY \
+ *       --ec_public_key_file=ec_public.pem \
+ *       --rsa_certificate_file=rsa_cert.pem \
+ *       --service_account_json=service_account.json
+ *
+ * Troubleshooting:
+ *
+ * If you get a 400 error when running the example, with the message "The API
+ * Key and the authentication credential are from different projects" it means
+ * that you are using the wrong API Key. Ensure that you are using the API key
+ * from Google Cloud Platform's API Manager's Credentials page.

+# Google Cloud IoT Core NodeJS MQTT example
+
+This sample app publishes data to Cloud Pub/Sub using the MQTT bridge provided
+as part of Google Cloud IoT Core.
+
+Note that before you can run this sample, you must register a device as
+described in the parent README.
+
+# Setup
+
+Run the following command to install the library dependencies for NodeJS:
+
+    npm install
+
+# Running the sample
+
+The following command summarizes the sample usage:
+
+  Usage: cloudiot_mqtt_example_nodejs [options]
+
+  Example Google Cloud IoT Core MQTT device connection code.
+
+  Options:
+
+    -h, --help                         output usage information
+    --project_id <project_id>          GCP cloud project name.
+    --registry_id <registry_id>        Cloud IoT Core registry id.
+    --device_id <device_id>            Cloud IoT Core device id.
+    --private_key_file <key_file>      Path to private key file.
+    --algorithm <algorithm>            Encryption algorithm to generate the JWT. Either RS256 or ES256
+    --cloud_region [region]            GCP cloud region
+    --num_messages [num]               Number of messages to publish.
+    --mqtt_bridge_hostname [hostname]  MQTT bridge hostname.
+    --mqtt_bridge_port [port]          MQTT bridge port.
+
+For example, if your project ID is `blue-jet-123`, your service account
+credentials are stored in your home folder in creds.json and you have generated
+your credentials using the shell script provided in the parent folder, you can
+run the sample as:
+
+    node cloudiot_mqtt_example_nodejs.js \
+        --project_id=blue-jet-123 \
+        --registry_id=my-registry \
+        --device_id=my-node-device \
+        --private_key_file=../rsa_private.pem \
+        --algorithm=RS256
+
+# Reading the messages written by the sample client
+
+1. Create a subscription to your topic.
+
+    gcloud beta pubsub subscriptions create \
+        projects/your-project-id/subscriptions/my-subscription \
+        --topic device-events
+
+2. Read messages published to the topic

+/**
+ * NodeJS sample of connecting to Google Cloud IoT Core via MQTT, using JWT.
+ *
+ * <p>This example connects to Google Cloud IoT Core via MQTT, using a JWT for
+ * device authentication. After connecting, by default the device publishes 100
+ * messages to the device's MQTT topic at a rate of one per second, and then
+ * exits.
+ *
+ * <p>Before you can run this sample, you must register a device as described
+ * in the parent README.
+ *
+ * <p>Usage example:
+ *
+ * <pre>
+ *   $ npm install
+ *   $ nodejs cloudiot_mqtt_example_nodejs.js \
+ *       --project_id=my-project-id \
+ *       --registry_id=my-registry-id \
+ *       --device_id=my-device-id \
+ *       --private_key_file=rsa_private.pem \
+ *       --algorithm=RS256"
+ * </pre>
