Just yesterday I attempted to explain to my colleagues (who have been mainframe developers all their life) the concept of having multiple remote repositories and different possible setups. I think I explained adding remote repositories well enough, and mentioned the use cases for such a setup -- having only read access from a repository and needing to develop in a fork while keeping up to date with the original.

Does anyone have a good analogy for this? I think they understood for the most part, but explaining things better is something I have been really trying to improve on in the workplace lately.
