In our guide - we spent a bit of time discussing users and various shells.
here is the conversation

in my experience teaching this topic, many don't know / understand bash / shell / windows terminal etc and as such this could become a stumbling block. It could be worth us having a page somewhere that helps users understand what shell they are using and associated setup items that they may need to consider.
