+## Update Swarm Images ##
+i wanted to update swarm images whenever there is a new image available (even at the risk of breaking something)
+
+it seems watchtower can't do this for swarm stacks/services - only one off containers.
+
+I found this great container from https://github.com/djmaze/shepherd  
+
+### placement considerations
+
+Must be placed on a manager node.
+
+### Config notes
+By default it will refresh all services, exclude any you dont want it to touch.
+I am not using apprise for this yet, but will be implementin apprise soon.
