The server row: the commits that are on originYour clone: an independent copy of the historyThe mill is git clone: it stamps the whole historyThe board holds main and origin/main separatelygit clone copies the whole history, not only the files, and adds two things. origin is a name for the server. origin/main is a bookmark of where the server's main was when you cloned. Your main moves when you commit. origin/main moves only when you fetch or push, which is why the two arms can part.
