+# Getting Started with Stackdriver Logging and the Google Cloud Client libraries
+
+[Stackdriver Logging][logging]  allows you to store, search, analyze, monitor,
+and alert on log data and events from Google Cloud Platform and Amazon Web
+Services.
+These sample Java applications demonstrate how to access the Cloud Storage API using
+the [Google Cloud Client Library for Java][google-cloud-java].
+
+[logging]: https://cloud.google.com/logging/
+[google-cloud-java]: https://github.com/GoogleCloudPlatform/google-cloud-java
+
+## Quickstart
+
+Install [Maven](http://maven.apache.org/).
+
+Build your project with:
+
+	mvn clean package -DskipTests
+
+You can then run a given `ClassName` via:
+
+	mvn exec:java -Dexec.mainClass=com.example.logging.ClassName \
+	    -DpropertyName=propertyValue \
+		-Dexec.args="any arguments to the app"
+
+### Writing a log entry (using the quickstart sample)
+
+    mvn exec:java -Dexec.mainClass=com.example.logging.QuickstartSample \
+        -Dexec.args="my-log"
