+This repo contains example projects which show how to use different (not only) Java technologies.

+## Java Modules
+All Java modules require **Java 11** to compile and run.
+
+### Building with Gradle
+
+Each module should be an independent build and can be built by calling `./gradlew clean build` in the module directory. 
+
+All modules are listed in [build-all.sh](build-all.sh) to run in the CI pipeline.
+
+### Non-Java Modules
+
+Some folders contain non-Java projects. For those, refer to the README within the module folder.

-# Consumer-Driven-Contract Test for a Feign Consumer
- 
-This repo contains an example of consumer-driven-contract testing for a Feign client
-that consumes a REST API provided by the module `pact-spring-data-rest-provider`.
-
-The contract is created and verified with [Pact](https://docs.pact.io/).
-
-## Companion Blog Post
-
-The Companion Blog Post to this project can be found [here](https://reflectoring.io/consumer-driven-contracts-with-pact-feign-spring-data-rest/).
-
-## Running the application
-
-The interesting part in this code base is the class `ConsumerPactVerificationTest`.
-You can run the tests with `gradlew test` on Windows or `./gradlew test` on Unix.

-# Consumer-Driven-Contract Test for a Spring Data Rest Provider
- 
-This repo contains an example of consumer-driven-contract testing for a Spring
-Data REST API provider. The corresponding consumer to the contract is
-implemented in the module `pact-feign-consumer`.
-
-The contract is created and verified with [Pact](https://docs.pact.io/).
-
-## Companion Blog Post
-
-The Companion Blog Post to this project can be found [here](https://reflectoring.io/consumer-driven-contracts-with-pact-feign-spring-data-rest/).
-
-## Running the application
-
-The interesting part in this code base is the class `ProviderPactVerificationTest`.
-You can run the tests with `gradlew test` on Windows or `./gradlew test` on Unix.
