+[![CI](https://github.com/thombergs/code-examples/workflows/CI/badge.svg)](https://github.com/thombergs/code-examples/actions?query=workflow%3ACI)
 
 This repo contains example projects which show how to use different (not only) Java technologies.
 The examples are usually accompanied by a blog post on [https://reflectoring.io](https://reflectoring.io).
 
-See the READMEs in each subdirectory of this repo for more information on each module.
-
-## 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.
+See the READMEs in each subdirectory of this repo for more information on each module.

+# Usage Examples of LocalStack
+
+
+### Reference Documentation 
+
+Two examples of using LocalStack is provided here. Make sure you have Docker installed and docker engine is started. The examples use Java 14. Make changes to pom.xml if you are using a lower version of Java.
+
+* JUnit Test classes : JUnit Jupiter tests start LocalStack in a Docker container when the test runs and stops the container when test ends.
+* Spring Boot application: REST API for creating a customer profile in AWS DynamoDB and store profile picture in S3.
