+
+### Overview
+This Maven project contains the Java code for the Couchbase entities and Spring services
+as described in the tutorials, as well as a unit/integration test
+for each service implementation.
+
+### Working with the Code
+The project was developed and tested using Java 7 and 8 in the Eclipse-based
+Spring Source Toolkit (STS) and therefore should run fine in any
+recent version of Eclipse or another IDE of your choice
+that supports Java 7 or later.
+
+### Building the Project
+You can also build the project using Maven outside of any IDE:
+```
+mvn clean install
+```
+
+### Package Organization
+Java classes for the intro tutorial are in the
+org.baeldung.couchbase.intro package.
+
+Java classes for the Spring service tutorial are in the
+org.baeldung.couchbase.spring package hierarchy.
+
+Java classes for the Asynchronous Couchbase tutorial are in the
+org.baeldung.couchbase.async package hierarchy.
+
+
+### Running the tests
+The test classes for the Spring service tutorial are:
+- org.baeldung.couchbase.spring.service.ClusterServiceTest
+- org.baeldung.couchbase.spring.person.PersonCrudServiceTest
+
+The test classes for the Asynchronous Couchbase tutorial are in the
+org.baeldung.couchbase.async package hierarchy:
+- org.baeldung.couchbase.async.service.ClusterServiceTest
+- org.baeldung.couchbase.async.person.PersonCrudServiceTest
+
+The test classes may be run as JUnit tests from your IDE
+or using the Maven command line:
+```
+mvn test
+```
