Every value in a template is inferred from a machine class; not one of them comes from your machine. Change only the ones you actually know and leave the rest — each one you fill in is one assumption fewer. The parameter number next to each field is where to find it on the machine's parameter screen.
Below is exactly what will be downloaded. It updates as you edit and is validated by the engine. You cannot download it while validation fails — so you will never end up with a file the engine cannot read. The header lists the fields you changed, so later you can tell which values are real and which are still the template's assumptions.
