Hello! I've noticed something unusual when checking this PR at commit
141fe5849f04fde8b417ed532dca52514096ab80:

• The page pages/common/docker-image-ls.md seems to be a copy of pages/common/docker-images.md (53% matching).
• The page pages/common/docker-image-rm.md seems to be a copy of pages/common/docker-rmi.md (61% matching).

Is this intended? If so, just ignore this comment. Otherwise, please double-check the commits.

I didn't like the extra changes I made. Those will have to be decided on a later date.
