+# Automatic
+### Using Kafka with a Java Producer and Consumer
+
+Run the demo script
+It will check prerequisites, build a consumer and producer, and run them with kafka and ICS.
+
+```shell
+./start.sh
+```
+Or run the other script to bring up RedPanda on port 8888 and NONRTRIC control panel UI on port 8181
+
+```shell
+./red.sh
+```
+
+For a faster execution you can add:
+
+--skip-build to skip creating the app jar and building the docker images
+
+--no-console to skip running RedPanda and NONRTRIC control panel
+
+```shell
+./red.sh --skip-build --no-console
+```
+# Manual
+### Run Kafka in a container
+
+```shell
+docker-compose up -d kafka-zkless
+```
+
+### Starting the REST application individually
+
+In a new terminal window:
+
+```shell
+mvn spring-boot:run
+```
+
+### Starting a producer
+
+```shell
+sh ./runproducer.sh
+```
+
+### Starting a Consumer
+
+```shell
+sh ./runproducer.sh
+```
+
+## Reading the logs

+A sample of the output is as follows:
