 ## 0.9.1 (release date: 2013-11-12)
 
  * Improved init process script (`/sbin/my_init`): it now handles shutdown correctly. Previously, `docker stop` would not have any effect on `my_init`, causing the whole container to be killed with SIGKILL. The new init process script gracefully shuts down all runit services, then exits.

-# A minimal Docker base image with a correct and usable system
+# A minimal Ubuntu base image modified for Docker-friendliness
 
-Baseimage-docker is a [Docker](http://www.docker.io) image meant to serve as a good base for any other Docker container. It contains a minimal base system with the most important things already installed and set up correctly.
+Baseimage-docker is a special [Docker](http://www.docker.io) image that is configured for correct use within Docker containers. It is Ubuntu, plus modifications for Docker-friendliness. You can use it as a base for your own Docker images.
+
+Baseimage-docker is available for pulling from on [the Docker registry](https://index.docker.io/u/phusion/baseimage/)!

+### What are the problems with the stock Ubuntu base image?
+
+Ubuntu is not designed to be run inside docker. Its init system, Upstart, assumes that it's running on either real hardware or virtualized hardware, but not inside a Docker container. But inside a container you don't want a full system anyway, you want a minimal system. But configuring that minimal system for use within a container has many strange corner cases that are hard to get right if you are not intimately familiar with the Unix system model. This can cause a lot of strange problems.
+
+Baseimage-docker gets everything right. The "Contents" section describes all the things that it modifies.
+
 ### Why use baseimage-docker?
 
-Why use baseimage-docker instead of doing everything yourself in Dockerfile?
+You can configure the stock `ubuntu` image yourself from your Dockerfile, so why bother using baseimage-docker?
 
+ * Configuring the base system for Docker-friendliness is no easy task. As stated before, there are many corner cases. By the time that you've gotten all that right, you've reinvented baseimage-docker. Using baseimage-docker will save you from this effort.
  * 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.
