+BigTop Data Generators
+======================
+
+A collection of synthetic data generators and supporting libraries
+for building blueprints, smoke testing, and timing operations.
+
+The following data generators are included so far:
+
+* BigPetStore -- generates customers, stores, products, and transactions for a fictional chain of pet stores
+* BigTop Name Generator -- generates names by sampling from U.S. Census data
+
+We have the following libraries:
+
+* BigTop Samplers -- collection of samplers, PDFs, and weight function interfaces and implementations
+
+Building
+--------
+To simplify dependency management, Gradle's multi-project support is used.  Each project
+defines its dependencies in terms of other projects and a holistic `settings.gradle` file
+is provided to make building easy.  Just run the following from the `bigtop-data-generators`
+directory:
+
+    $ gradle build
+
+The resulting jar files will be located under `build/libs` directory of each project.
+
+Jar files can be installed to a local Maven cache to simplify integration by external projects:
+
+    $ gradle install
+
+You can then define the dependencies via Maven.
