  * It reduces the time needed to write a correct Dockerfile. You won't have to worry about the base system and can focus on your stack and your app.
  * It sets up the base system **correctly**. It's very easy to get the base system wrong, but this image does everything correctly.
  * It reduces the time needed to run `docker build`, allowing you to iterate your Dockerfile more quickly.
+ * It reduces download time during redeploys. Docker only needs to download the base image once: during the first deploy. On every subsequent deploys, only the changes you make on top of the base image are downloaded.
