 ### 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.

  * 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 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.

 ### Does Baseimage-docker advocate "fat containers" or "treating containers as VMs"?
 
-There are people who are under the impression that Baseimage-docker advocates treating containers as VMs, because of the fact that Baseimage-docker advocates the use of multiple processes. Therefore they are also under the impression that Baseimage-docker does not follow the Docker philosophy. Neither of these impressions are true.
+There are people who think that Baseimage-docker advocates treating containers as VMs because Baseimage-docker advocates the use of multiple processes. Therefore, they also think that Baseimage-docker does not follow the Docker philosophy. Neither of these impressions are true.
 
 The Docker developers advocate running a single *logical service* inside a single container. But we are not disputing that. Baseimage-docker advocates running multiple *OS processes* inside a single container, and a single logical service can consist of multiple OS processes.
 
-It follows from this that Baseimage-docker also does not deny the Docker philosophy. In fact, many of the modifications we introduce are explicitly in line with the Docker philosophy.
