 ### Need to clean house first?
+
 Make sure you are starting with a clean state. For example, do you have other Laradock containers and images?
 Here are a few things I use to clean things up.
 
 - Delete all containers using `grep laradock_` on the names, see: [Remove all containers based on docker image name](https://linuxconfig.org/remove-all-containners-based-on-docker-image-name).
+
 `docker ps -a | awk '{ print $1,$2 }' | grep laradock_ | awk '{print $1}' | xargs -I {} docker rm {}`
 
 - Delete all images containing `laradock`.
+
 `docker images | awk '{print $1,$2,$3}' | grep laradock_ | awk '{print $3}' | xargs -I {} docker rmi {}`
 **Note:** This will only delete images that were built with `Laradock`, **NOT** `laradock/*` which are pulled down by `Laradock` such as `laradock/workspace`, etc.
 **Note:** Some may fail with:
 `Error response from daemon: conflict: unable to delete 3f38eaed93df (cannot be forced) - image has dependent child images`
 
 - I added this to my `.bashrc` to remove orphaned images.
-    ```
-    dclean() {
-        processes=`docker ps -q -f status=exited`
-        if [ -n "$processes" ]; thend
-          docker rm $processes
-        fi
-
-        images=`docker images -q -f dangling=true`
-        if [ -n "$images" ]; then
-          docker rmi $images
-        fi
-    }
-    ```

+    if [ -n "$images" ]; then

+    fi
+}
+```
 
 - If you frequently switch configurations for Laradock, you may find that adding the following and added to your `.bashrc` or equivalent useful:
+
 ```
 # remove laravel* containers
 # remove laravel_* images
