+[![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.

+# RDS Hello World Application
+
+This is a simple Spring Boot application which requires access to a PostgreSQL database.
+
+The application has a single endpoint `/hello` which prints out if the database connection was successful.
+
+Get it in a Docker image via `docker pull reflectoring/aws-rds-hello-world`.
+
+Use the image instead of your real application to test AWS CloudFormation stacks which need access to a database.
+
+## Testing AWS RDS connectivity with this application
+
+1. Create an RDS PostgreSQL database with the AWS console.
+2. Note the endpoint of your RDS database in the AWS console.
+3. Deploy the Docker container `reflectoring/aws-rds-hello-world` into AWS instead of your real application (this could be via a CloudFormation stack, manually, or however you are deploying your app).
+4. Configure your deployment in a way that Docker will pass the coordinates to your RDS database as environment variables, equivalent to this command:
+    ``` 
+    docker run \
+      -e SPRING_DATASOURCE_URL=':'<RDS-ENDPOINT>:5432/postgres \
+      -e SPRING_DATASOURCE_USERNAME=<USERNAME> \
+      -e SPRING_DATASOURCE_PASSWORD=<PASSWORD> \
+      -p 8080:8080 reflectoring/aws-rds-hello-world
+    ```
+5. If the Spring Boot application can connect to the database, it will start up sucessfully and serve a message on the endpoint `/hello`.
