+Note that two of the containers are build from Dockerfiles, while the other three are images on Docker Hub. To learn more about how they're built, you can examine each of the Dockerfiles in the two directories: `voting-app`, `result-app`. We included the code for the Java worker in `worker` but pre-built the image to save on downloads.
 
 The Compose file also defines two networks, front-tier and back-tier. Each container is placed on one or two networks. Once on those networks, they can access other services on that network in code just by using the name of the service. To learn more about networking check out the [Networking with Compose documentation](https://docs.docker.com/compose/networking/).
