ELI5: Explain Like I'm 5

Checklist

A checklist is when you make a list of tasks that you need to do. It helps you remember all the things that you need to do so you don’t forget something important. For example, when you’re going on a vacation, you might make a checklist of things like getting your plane tickets, packing your clothes, and getting your passport ready. That way, you won’t forget any of the important things to do before you leave!
