 The first time the tests are run, Docker will create the container images that are used to
 run the tests. This can take several minutes, particularly if you have a slow network
 connection. Subsequent runs will be faster as the images are cached locally. You can run

 == Cleaning up
 
 If you want to reclaim the disk space used by the cached images (at the expense of having
 to wait for them to be downloaded and rebuilt the next time you run the tests), you can
-use `docker images` to list the images and `docker rmi <image>` to delete them. See
