 - **v0.7.5**:
-    - Added new option **DaysKept**; `-k N` and `-K`:
+    - Added new option **BackupForDays**; `-b N` and `-B`:
       - Backup an image before pulling a new version for easy rollback in case of breakage.
       - Removes backed up images older than *N* days.
       - List currently backed up images with `-K`.

 Pass `-x N` where N is number of subprocesses allowed, experiment in your environment to find a suitable max!  
 Change the default value by editing the `MaxAsync=N` variable in `dockcheck.sh`. To disable the subprocess function set `MaxAsync=0`.
 
-## Image Backups; `-k N` to backup previous images as custom (retagged) images for easy rollback

+## Image Backups; `-b N` to backup previous images as custom (retagged) images for easy rollback
+When the option `BackupForDays` is set **dockcheck** will store the image being updated as a backup, retagged with a different name and removed due to age configured (*BackupForDays*) in a future run.  
 Let's say we're updating `b4bz/homer:latest` - then before replacing the current image it will be retagged with the name `dockcheck/homer:2025-10-26_1132_latest`
 - `dockcheck` as repo name to not interfere with others.
 - `homer` is the image.
 - `2025-10-26_1132` is the time when running the script.
 - `latest` is the tag of the image.
 
-Then if an update breaks you could temporarily roll back to the previoius working state by changing the docker compose image to `image: dockcheck/homer:2025-10-26_1132_latest` and get it up and running again, then continue troubleshooting the breaking update.  
+Then if an update breaks, you could restore the image by stopping the container, delete the new image, eg. `docker rmi b4bz/homer:latest`, then retag the backup as latest `docker tag dockcheck/homer:<date>_latest b4bz/homer:latest`.  
+After that, start the container again (now with the backup image active) and it will be updated as usual next time you run dockcheck or other updates.
 
-The backed up images will be removed if they're older than *DaysKept* value (passed as `-k N` or set in the `dockcheck.config` with `DaysKept=N`) and then pruned.  
-If configured for eg. 7 days, force earlier cleaning by just passing a lower number of days, eg. `-k 2` to clean everything older than 2 days.  
-Backed up images will not be removed if neither `-k` flag nor `DaysKept` config variable is set.
+The backed up images will be removed if they're older than *BackupForDays* value (passed as `-b N` or set in the `dockcheck.config` with `BackupForDays=N`) and then pruned.

-Use the capital option `-K` to list currently backed up images. Or list all images with `docker images`.  
+Use the capital option `-B` to list currently backed up images. Or list all images with `docker images`.  
 To manually remove any backed up images, do `docker rmi dockcheck/homer:2025-10-26_1132_latest`.
