Hi team, I'm trying out Prefect. Can someone explain like I'm 5 how do I go from flow/task to deployment and why the task actually run on my computer after I ran the serve? I figured I should make a project like other tools and then submit the package to Prefect to run on Prefect server, is it wrong? It seem to me I have to open a CMD and let it hang around every time I deploy a new project(?).
