 This is the Java/Spring version of the Event Sourcing/CQRS money transfer example application.
 
-It consists of the following modules:
+This application consists of three microservices:
+
+  * Account Service - the command side business logic for Accounts
+  * Money Transfer Service - the command side business logic for Money Transfers
+  * Query service - query side implementation of a MongoDB-based, denormalized view of Accounts and MoneyTransfers
+   
+The Account Service consists of the following modules:
+
+  * commandside-backend-accounts - the Account aggregate
+  * commandside-web-accounts - a REST API for creating and retrieving Accounts
+ 
+The Money Transfer Service consists of the following modules:
+
+  * commandside-backend-transactions - the MoneyTransfer aggregate  
+  * commandside-web-transactions - a REST API for creating and retrieving Money Transfers
+ 
+The Query Service consists the following modules:
+
+  * queryside-backend - MongoDB-based, denormalized view of Accounts and MoneyTransfers
+  * queryside-web - a REST API for querying the denormalized view
+
+In order to be used with the embedded Event Store, the three services are currently packaged as a single monolithic web application:
+
+  * monolithic-web - all-in-one, monolithic packaging of the application
+
+As well as the above modules there are also:
 
   * common-backend - code that is shared between the command side and the query side, primarily events and value objects
-  * commandside-backend - the business logic, which consists of Account and MoneyTransfer aggregates
-  * queryside-backend - MongoDB-based, denormalized view of Accounts and MoneyTransfers
-  * commandside-web - a REST API for creating and retrieving Accounts and MoneyTransfers
-  * queryside-web - a REST API for querying the MongoDB-based, denormalized view of Account
-  * monolithic-web - all-in-one, monolithic packaging of the application
+  * backend-integration-tests - integrations tests for the backend
