-The projects that require middleware (i.e. Redis) for testing generally
-require that a local instance of [Docker](https://www.docker.com/get-started) is installed and running.
+For hints on how to build the project look in `.travis.yml` if there
+is one. There should be a "script" and maybe "install" command. Also
+look at the "services" section to see if any services need to be
+running locally (e.g. mongo or rabbit).  Ignore the git-related bits
+that you might find in "before_install" since they're related to setting git
+credentials and you already have those.
 
+The projects that require middleware generally include a
+`docker-compose.yml`, so consider using
+https://docs.docker.com/compose/[Docker Compose] to run the middeware servers
+in Docker containers. See the README in the
+https://github.com/spring-cloud-samples/scripts[scripts demo
+repository] for specific instructions about the common cases of mongo,
+rabbit and redis.
+
+NOTE: If all else fails, build with the command from `.travis.yml` (usually
+`./mvnw install`).
