+- Not working well with containers created by **Portainer**.
+- **Watchtower** might cause issues due to retagging images when checking for updates (and thereby pulling new images).
 
 ## :warning: `-r flag` disclaimer and warning
 **Wont auto-update the containers, only their images. (compose is recommended)**  
 `docker run` dont support using new images just by restarting a container.  
 Containers need to be manually stopped, removed and created again to run on the new image.
 
+## :wrench: Debugging
+If you hit issues, you could check the output of the `extras/errorCheck.sh` script for clues. 
+Another option is to run the main script with debugging in a subshell `bash -x dockcheck.sh` - if there's a particular container/image that's causing issues you can filter for just that through `bash -x dockcheck.sh nginx`.
