 The image contains a directory "/checkout", which is a copy of your
 local Emacs git repository.  Emacs has been built in this directory
 via "make bootstrap".  In order to use the image, start a container
 like
 
-  docker run --interactive --env EMACS_EMBA_CI=1 --name emacs-inotify \
+  docker run --interactive --tty --env EMACS_EMBA_CI=1 --name emacs-inotify \
