 ## How do I use it myself?
 I run `lstags` inside a Cron Job on my Kubernetes worker nodes to poll my own Docker registry for a new [stable] images.
-**NB!** `lstags` itself doesn't pull images, I use `grep`, `aws` and `xargs` to filter its output and pass it then do `docker pull`:
 ```
-lstags -r registry.ivanilves.local -u myuser -p mypass tools/sicario \
- | egrep "^(ABSENT|CHANGED).*:v1\.[0-9]+\.[0-9]+$" \
- | awk '{print $NF}' ] \
- | xargs -i docker pull {}
+lstags --pull-images -u myuser -p mypass registry.ivanilves.local/tools/sicario~/v1\\.[0-9]+$/ 
 ```
 ... and following cronjob runs on my CI server to ensure I always have latest Ubuntu 14.04 and 16.04 images to play with:
 ```
-lstags ubuntu | egrep "^(ABSENT|CHANGED).*:1[46].04$" | awk '{print $NF}' | xargs -i docker pull {}
+lstags --pull-images ubuntu~/^1[46]\\.04$/"
 ```
 My CI server is connected over crappy Internet link and pulling images in advance makes `docker run` much faster. :wink:
