 ### Start a container
 A container is an instance created from an image, that can be run and that keeps running until its main process exits. Or until the user stops the container. 
 
 The simplest way to start a container from image is ``docker run``. It also pulls the image for you if it is not locally available. For more advanced use, refer to ``docker create``.
 
-Note that stopped containers are not destroyed, unless you specify ``--rm``. To view all created, running and stopped containers, enter:

-Some containers may be designed or configured to be restarted, others are not. Note that both network ports and volumes of a container are created on start, and not editable later.

 ### Access a running container
 A running container is accessible using ``docker exec``, or ``docker copy``. You can use ``exec`` to start a root shell in the Shaarli container:
 ```bash
 $ docker exec -ti <container-name-or-id> bash
 ```
-Note the names and ID's of containers are list in ``docker ps``. You an even type only one or two letters of the ID, given they are unique.

 Access can also be through one or more network ports, or disk volumes. Both are specified on and fixed on ``docker create`` or ``run``.

 ### Docker disk use
 Trying out different images can fill some gigabytes of disk quickly. Besides images, the docker volumes usually take up most disk space.
