 * Builds from the `Dockerfile` in the current directory.
 * Forwards the exposed port 5000 on the container to port 5000 on the host machine.
 * Mounts the current directory on the host to `/code` inside the container allowing you to modify the code without having to rebuild the image.
-* Links the web container to the Redis service.
 
 The `redis` service uses the latest public [Redis](https://registry.hub.docker.com/_/redis/) image pulled from the Docker Hub registry.
