title: What's the difference between 'down' and 'rm' in docker/docker-compose?
body: <p>The docs for <a href="https://docs.docker.com/compose/reference/down/" rel="noreferrer"><code>docker-compose down</code></a>, <a href="https://docs.docker.com/compose/reference/rm/" rel="noreferrer"><code>docker-compose rm</code></a>, and <a href="https://docs.docker.com/engine/reference/commandline/rm/" rel="noreferrer"><code>docker rm</code></a> all read very similarly.  What's the difference? And when would you use one over the others?</p>
