 Where `[...]` is arguments for `<SCRIPT>`. `<SCRIPT>` is locating on the host (and copying to target image until execution is finished). Leave `img-chroot <IMAGE>` without any argument for enter to `/bin/bash` on the target image.
 
 ### Resize an image (minimize & maximize)
 
 ```bash
-docker run --privileged -it --rm -v /dev:/dev -v $(pwd):/mnt urpylka/img-tool:v0.4 img-resize <IMAGE> [NEW_SIZE]
+docker run --privileged -it --rm -v /dev:/dev -v $(pwd):/mnt urpylka/img-tool:0.4 img-resize <IMAGE> [NEW_SIZE]
 ```
 
 > If you leave `NEW_SIZE` parameter empty, program return posible minimum size. It works by **resize2fs** and maybe more than actually (for take minimum size minimize image a few times). It may also work poorly if used 1K, 2K block in FS (more on [man7.org](http://man7.org/linux/man-pages/man8/resize2fs.8.html)).
