+You can build all the projects by running the `./build-all-projects.sh` on Mac/Linux systems and then going to each individual folder and running the jars using the `java -jar build/libs/sam<application_name>` command.

 Please refer to the individual readme files on instructions of how to run the services. For demo, you can run the applications in the same order listed above.
