Mongo: shared vs simple tags

Hi,

Mongo repository description says this is the place to ask for help.

What’s the difference between simple and shared tags? Is there a better place to ask?

Thanks in advance.

From what I can see, simple tags unambiguously identify an image, while shared tags gets assigned to several images. Thus, when you tell it to run an image by a shared tag, one of those get chosen based on your os/arch.
