+Bigtable-hello-j8
+=================
+
+Moves the Bigtable Hello World application to Google App Engine Standard for Java 8.
+
+
+* [Java 8](http://www.oracle.com/technetwork/java/javase/downloads/index.html)
+* [Maven](https://maven.apache.org/download.cgi) (at least 3.3.9)
+* [Gradle](https://gradle.org)
+* [Google Cloud SDK](https://cloud.google.com/sdk/) (aka gcloud)
+
+Initialize the Google Cloud SDK using:
+
+    gcloud init
+
+    gcloud auth application-default login
+
+Then you need to [Create a Cloud Bigtable Instance](https://cloud.google.com/bigtable/docs/creating-instance)
+
+
+## Using Maven
+
+### Run Locally
+
+    mvn -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID appengine:run
+
+### Deploy to App Engine Standard for Java 8
+
+    mvn -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID appengine:deploy
+
+### Run Integration Tests
+
+    mvn -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID verify
+
+## Using Gradle
+
+### Run Locally
+
+    gradle -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID appengineRun
+
+### Integration Tests & Deploy to App Engine Standard for Java 8
+
+    gradle -Dbigtable.projectID=PROJECTID -Dbigtable.instanceID=INSTANCEID appengineDeploy
+
+As you add / modify the source code (`src/main/java/...`) it's very useful to add
+[unit testing](https://cloud.google.com/appengine/docs/java/tools/localunittesting)
+to (`src/main/test/...`).  The following resources are quite useful:
+
+* [JUnit4](http://junit.org/junit4/)
+* [Mockito](http://mockito.org/)
+* [Truth](http://google.github.io/truth/)
+
+### When done
+
+Cloud Bigtable Instances should be [deleted](https://cloud.google.com/bigtable/docs/deleting-instance)
+when they are no longer being used as they use significant resources.
