+# App Engine Flexible Environment - Cloud Datastore Sample
+
+## Application code
+
+The sample application logs, retrieves, and displays visitor IPs. You
+can see that a visit is a Cloud Datastore entity of kind `Visit`, and
+is saved using the Dataset `save` method. Then, the ten most recent
+visits are retrieved in descending order by building a Query, and
+using the Dataset `run` method.
+
+## Run
+
+Make sure `gcloud` is installed and authenticated. You can find your
+project id with `gcloud config list`.
+
+
+```
+export GOOGLE_CLOUD_PROJECT=<your-project-id>
+bundle
+bundle exec ruby ./app.rb
+```
+
+## Deploy
+
+```
+gcloud app deploy
+```
+
+## Test
+
+Note: the tests do a live deploy to App Engine
+
+Put a `client_secrets.json` file for a service account in the root of
+your repo.
+
+```
+gcloud auth activate-service-account --key-file ../../client_secrets.json
+export TEST_DIR=appengine/datastore/
+bundle exec rspec
+```
