+## Cleaning up Docker images
+
+If you update your Docker container images regularly using something like [watchtower](https://containrrr.dev/watchtower/), you might have dangling images which are out-of-date and no longer associated with some of your running containers.
+
+So why not use `docker images prune` to reclaim that valuable disk space. For example, running this command on my Raspberry Pi shaved off about 9.66Gb of disk usage.
+
+As a bonus, you can save some additional space using `docker images prune --all`, which removes all unused Docker images.
+
+## Restarting all containers
+
+Sometimes you want to restart all your containers at once, such as after you've pulled the latest images for your containers.
+
+To do this, use `docker restart $(docker ps -q)`, this command instructs Docker to restart all containers using the container ids which are returned from `docker ps -q`.
