+# Cloud IoT Core Java Samples
+This folder contains Java samples that demonstrate an overview of the
+Google Cloud IoT Core platform.
+
+## Quickstart
+
+1. Install the gCloud CLI as described in [the device manager guide](https://cloud-dot-devsite.googleplex.com/iot/docs/device_manager_guide).
+2. Create a PubSub topic:
+
+    gcloud beta pubsub topics create projects/my-iot-project/topics/device-events
+
+3. Add the special account `[email protected]` to that
+PubSub topic from the [Cloud Developer Console](https://console.cloud.google.com)
+or by using the helper script in the /scripts folder.
+
+4. 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
+
+5. Use the `generate_keys.sh` script to generate your signing keys:
+
+    ./generate_keys.sh
+
+6. Create a device.
+
+    gcloud alpha iot devices create my-java-device \
+        --project=my-iot-project \
+        --region=us-central1 \
+        --registry=my-registry \
+        --public-key path=rsa_cert.pem,type=rs256
+
+7. Connect a sample device using the sample app in the `mqtt_example` folder.
+8. Learn how to manage devices programatically with the sample app in the
+`manager` folder.

+# Cloud IoT Core Java Device Management example
+
+This sample app demonstrates device management for Google Cloud IoT Core.
+
+Note that before you can run the 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 libraries and build the sample with
+Maven:
+
+mvn clean compile assembly:single
+
+## Running the sample
+
+The following command summarizes the sample usage:
+
+    mvn exec:java \
+        -Dexec.mainClass="com.google.cloud.iot.examples.DeviceRegistryExample" \
+        -Dexec.args="-project_id=my-project-id \
+            -pubsub_topic=projects/my-project-id/topics/my-topic-id \
+            -ec_public_key_file=/path/to/ec_public.pem \
+            -rsa_certificate_file=/path/to/rsa_cert.pem"
+
+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:
+
+    mvn exec:java \
+        -Dexec.mainClass="com.google.cloud.iot.examples.DeviceRegistryExample" \
+        -Dexec.args="-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"
