+Where argument 1 is a pointer to the build `deb` file that you'd like to make an image from and 'version_tag' is the tag you'd like to push to the Docker registry with.
 
 You can specify multiple tags by adding additional tag names to the end of the command. This is useful where a for example release 0.10.4 is made which also consitutes 'latest', '0.10-nightly', '0.10.4', '0.10' images.
