+# Cloud IoT Core Java HTTP example
+
+This sample app publishes data to Cloud Pub/Sub using the HTTP bridge provided
+as part of Google Cloud IoT Core.
+
+Note that before you can run the sample, you must configure a Google Cloud
+PubSub topic for Cloud IoT Core and register a device as described in the
+[parent README](../README.md).
+
+## Setup
+
+Run the following command to install the dependencies using Maven:
+
+    mvn clean compile
+
+## Running the sample
+
+The following command summarizes the sample usage:
+
+```
+    mvn exec:java \
+        -Dexec.mainClass="com.example.cloud.iot.examples.HttpExample" \
+        -Dexec.args="-project_id=<your-iot-project> \
+                     -registry_id=<your-registry-id> \
+                     -device_id=<device-id> \
+                     -private_key_file=<path-to-keyfile> \
+                     -message_type=<event|state> \
+                     -algorithm=<RS256|ES256>"
+```
+
+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 [`generate_keys.sh`](../generate_keys.sh) script
+provided in the parent folder, you can run the sample as:
+
+```
+    mvn exec:java \
+        -Dexec.mainClass="com.example.cloud.iot.examples.HttpExample" \
+        -Dexec.args="-project_id=blue-jet-123 \
+                     -registry_id=my-registry \
+                     -device_id=my-java-device \
+                     -private_key_file=../rsa_private_pkcs8 \
+                     -algorithm=RS256"
+```
+
+To publish state messages, run the sample as follows:
+
+```
+    mvn exec:java \
+        -Dexec.mainClass="com.example.cloud.iot.examples.HttpExample" \
+        -Dexec.args="-project_id=blue-jet-123 \
+                     -registry_id=my-registry \
+                     -device_id=my-java-device \
+                     -private_key_file=../rsa_private_pkcs8 \
+                     -message_type=state \
+                     -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
+
+```
+    gcloud beta pubsub subscriptions pull --auto-ack \
+        projects/my-iot-project/subscriptions/my-subscription
+```
