			The tool is meant as a low-level tool and is intended to deal with the plumbing of container. The expectaiton is is it is used by higher level container software (such as [[Docker]] and [[Podman]]) to provide an interface better suited at common tasks. However, it can be useful for learning how things work, small tests or building your own tooling.
