Feature request: when pulling an image, also create a local copy of the info text on docker hub.

When searching for images on hub.docker.com, the more popular ones usually have a lot of usage examples on the "Overview" tab on their page. When I prepare to go on train by downloading some docker images I might need, I also want to have a copy of the information at docker hub available offline in case I don't have internet on the train.

maybe the information could be made available by a docker CLI command like "docker man

Thanks for your suggestion; unfortunately, I don't think this will be possible to implement, because the descriptions on Docker Hub are part of the Docker Hub "UI", not the Docker Hub registry. This means that fetching these documents would a) not be tied to a specific image (some registries on Docker Hub provide different flavours/variations of an image), and b) it would only work with Docker hub, and not with any other registry (such as Google cloud registry, Amazon's registry, GitHub registry and so on).
